>calc 2 is considered a brainlet filter now
lmao call me when you take real analysis or distribution theory based PDE course

>10517413
I got B in calc 2 while meeting up on half of the lectures, barely doing any exercises and finally working hard for 2 weeks before the exam. I didn't understand the material very good and it was a terrible idea. Needless to say, with such a bad fundament, Real Analysis became my filter.

>>10517413
>How?
Literally fucked around didn't study. Still got A in the class.

Calc 2 is literally plug and chug. You just try u-sub, parts, trig-sub and partial fractions in that order with every exercise and you'll get an A.

>>10517583
calculus is the easy part of calc 2, the shit part is series and sequences. fuck that shit.

>>10517413
/sci/bros, let's be nice. this is clearly a highschooler /sci/ thread, and making undergrad posts like this:
>>10517417
will harm their precious little minds.

18yo anons, this is your safe space. no millenial science-anons will make you feel like brainlets from now on

Does this mean if I get an A in this class that I can go into all future math classes with worthy confidence?

>>10517413
I was wondering, are the contents of calc 2 standardized across the US? Here where I live there seems to be 2 ways it goes depending on the institution: One is like >>10517583 described, where you do u-subs, partial fractions and the like, and the other is ODE's and series. In the second case, they show most of the first stuff in Calc 1.

and the upper divs are usually easier cause they don't want to weed you out by then, they want you to graduate... but first you gotta pass these weeders which are made artificially difficult in order to be weeders...

>>10517417
this

>>10517787
My Calc 2 was gay because of series and having to remember all the criteria of different series for diverging and converging.

>>10517413

Calc 2 was one of my favorite classes, for it introduce the Taylor Series. And shortly after that I went down the sweet sweet rabbit hole of numerical methods, process controls, MEB's, etc. Doing math went from long methods and substitutions, to pressing the run button in matlab/similink until I get a ball park approximation. The fact that I could now on a whim make shitty models with shitty assumptions and get enough data and results to make it seem what I know what I'm doing, gives a brainlet like me a euphoria like no other.

>>10517796
Mine was too, but it was very quick (it was basically given so we could understand series as ODE's solutions and also MacLaurin)
I can barely remember any shit tho

Why can't anyone be honest? Yes, you know how to slove calculus problems but are you going to use it daily?

>>10517776
Funny cause I'm in calc 2 right now and I think series and sequences have been one of the easiest parts.

>>10517413
huh, jokes on you
i was filtered by calc1

>>10517781
Sorry OP. I am just a selfish loser.

>>10517787
In my US experience, u-sub was in calc 1, but trig sub, parts, partial fractions were calc 2. calc 2 also spent a lot of time on sequences and series, taylor series and such. Only touched a little bit on separable ODEs.

>>10517417
>lmao call me when you take real analysis or distribution theory based PDE course
Lol, it's the same brainlet shit. If you had problems with those, I have bad news for you.
I'd understand if you said étale cohomology or the Atiyah–Singer theorem

>>10518148
My school it's calc 1 ends with u-sub, calc2 is all integration, calc3 is sequences and series.

>>10517413
Kek

Calc 1 was harder for me. Reimann sums and related rates were obnoxious. The hard thing about Calc 2 is just remembering every little thing. I can't remember Calc 3 very well. If you take Diff Eq it's not bad, I liked it

>>10517787
Depends if a school operates in semeters or quarters. If you have quarters, first year calculus is broken up into 3 classes.

>>10518218
>I'd understand if you said étale cohomology or the Atiyah–Singer theorem

lol found the brainlet

seriously consider switching fields if you struggle with simple math anon

>>10519319

>>10520184
this.

Had an A in calc 2 up until Taylor Series. Fuck that shit. Dropped to a B.

>>10517806
bruh, if you aren't ingraining it at a subconscious level, in the same way you should ingrain arithmetic and algebra, to do quick maffs-- you're fucking up

It feels sort of weird to me, I'm in calc 2 now and having tons of fun, I feel like I'm understanding the material, but my grade isn't reflecting that. I find I'm always running out of time and/or making the dumbest god-damned mistakes (basic computational errors, losing track of signs/terms).I feel like such a freaking brainlet. Sorry for blog-posting

What is calc 2? In my school we only have single variable and multi variable calculus.

>>10520613
This probably just means you are not practicing enough.

>>10520613
same except I quite literally have bombed every multiple choice section
>inb4 multiple choice math questions

>>10520622
Calc 2 is pretty much more integration techniques (u-sub, integration by parts, trig integrals), volumes and work, natural log, exponential growth and decay stuff, L'Hopital's, Series and Sequences, parametric curves and polar coordinates.

>>10517413
>*filters you*

>*filters you*

>>10520622

Single variable calculus is Calc I and II.
Multi variable calculus is Calc III and Vector Calculus.

>>10517413
What year of university study is calculus 2 usually taken?

>>10520956
usually the first year or second.

>>10520964
Just had a look at a past paper for it. Why is it a filter? Also how come none of the questions ask for proofs?

>>10517776
I liked sequences and series and found it easier myself, but to each their own.

>>10517788

This. While I use calculus 2 and above in all courses, everything seems more intuitive and my professors actually explain why we're doing something and the most efficient way to go about solving a problem.

I've never used trig sub since, that was the only thing that fucked me up, but luckily it fucked up most of the class.

Is it better to take calc 2 online or in person? I failed it over the summer but I went to all the lectures and SI sessions so i think it was because my professor sucked ass at teaching

*filters thread*

>>10521960

Taking it in class is fine but you need to go home and practice problems after each lecture. You don't get points on the exam for listening you need to actually be able to solve shit yourself.

>>10520757
Ha.

>TA'ed for this class
>didn't stop a cheater during a midterm because they were cheating off a failing student

>>10517413
Which calc 2? My university has two calc 2s

Math 122 for businessfags
Math 222 for scientists & engineers

>>10519958
>cant even name something more complex

Funny how different our syllabus is.
What do you have in calc 1?

>>10522373
so basically 122 is the dumbed down version so business people wouldn't get hung up?

>>10522531
intro to derivatives and integrals and some of their uses

calc 1 is considered one of the easier math classes. I found it easier than college algebra and trig

>>10522776
>we live in a society v2
There were economic motivations behind the decisions that made this happen.

>>10517413
The CS majors are on >>>/g/

>>10517776
But series is easy? Your algebra is probably just bad.

>>10522776
I think so.
I took 121 (Business Calc 1) inbetween high school and college just to make sure I could hand calculus because I didn't take it in high school and had heard horror stories. I got an A so then I took 221 and then 222. They wouldn't let me skip to Calc 2 (222) because they said 121 wasn't sufficient coverage, I tried to petition but the School of Engineering said fuck no basically.

aren't you supposed to skip this with ap credit anyway

>>10522910
ap credit is a joke 99% colleges dont even take it into account and no matter what calc 1 and 2 and required courses

>>10517413
Calc 2 actually filtered me, so I went to a community college for the semester and passed it there

Bout to take pre-calc and I'm scared now bros. What's the iq requirement to be proficient in calc?

>>10522920
I don't know what my IQ is, but I do know that I'm not smart. I passed calc. You can handle it.

>>10522920
The way they teach it now-n-days the bar is pretty low. I would say 105 +/- 5 IQ points.

After reading this thread, I got really confused. I googled some things and just found out that what you burgers call "calculus III" is what we in hueBR call "calculus II".
Your classes are only half of a semester or you divide calculus in five parts?

>>10520672
i haven't had multiple choice on a math test since highschool algebra 2. the only choice questions i got in calc 3 this semester were identifying the surfaces via equations

You americans are pathetic.

Calc 2 was easy but diff eq actually raped my anus

>Muscle-building 101
>*filters me*
Why can't I build muscle?! Nothing works

>>10523747
Going off the posts I read on 4chan, Europeans all learn how to solve 2nd order partial differential equations by age 11. And they come out of the womb knowing every trig identity.

Us Americans, it's really a wonder how we function at all.

>>10517413

WHERE DID MY CLASS GO


WHAT THE FUCK IS GOING ON ??!?!


HELLLLLOOOOOOOOOOOOOOOOO?!?!?!?!?

>>10517562
I wish I went to your uni.

>>10517413
is calc 2 multivariable calculus?

I always cringe at how americans find calculus so special and hard

>>10517413
I study in Germany, so I assume your Calc 2 is our "Analysis II" as that deals with multidimensional differentiation and integration, multidimensional Taylor approximation, Fourier-Series, etc.

Those weren't that bad, but for some reason we also had a bunch of Topology, with Normed Vector Spaces, Metric Spaces, Compact Spaces, Series and Funktions in all sorts of different Spaces, Banach fixed-point theorem…
I really hated that shit, way to abstract for brainlet me.

>>10524151
Also ignore filename, I'm not a french retard, I cringe even more at french retards than at americans

>>10524152
Lmao eurobro i don't think that's what's he's talking about, i think it's the amerishart version of calc 2 where they learn u-sub and integration by part for single variable functions.

>>10524264
no it's not you retard stop trying jewish tricks to your advabtage, burger

mods delete this thread plz

>>10524264
Isn't that calc 1, "Analysis 1" like >>10522531
mentioned.
Then what do burgers do in calc 1?

>>10524325
they learn to differentiate.

>>10517413
That's not CALC 3-4

>>10517776
We're doing that now, and I've thought it was pretty easy. What really fucked me up was the trig sub, probably just because I never had a good trig education.

>>10517796
>remember
There's nothing you have to memorize. It's all just applying the concepts of calc 1 in order to know whether something will show series convergence via common sense.

>>10520121
Underrated

>>10524151
>>10524153
For being so smart allegedly, Euros are pretty fucking retarded. Of course you're going to see more Americans than, say, Italians or Swedes complain about calculus.

Because there's way more fucking Americans than Swedes, LA alone has a bigger population than Sweden. You fucking retard.

>>10522231

Actually taking calc2 was a horrible time, almost failed it three times, now on my way to failing ode for the first time.
I just want to get past this engineering shit and get to proofs and analysis courses.

>>10524349
>they learn to differentiate.
Yeah, we did that too, for like 2 or 3 weeks, but there was a whole bunch of other stuff to do in this semester.

Our calc1 "Analysis I" looked somewhat like this:
logic and proofs, sets of numbers/basic set theory, sequences, limes, series, functions, <insert beforementioned 2-3 weeks differentiation>, l'hostpital, Taylor series, intro to Integral including u-sub/partial

>>10524506
Any 16 week semester that covers that much material clearly would not be able to go into any depth

Why are you bragging about having a class like this? The standards and exam questions would be laughably simple.

>>10524375
I'm an undergraduate taking graduate math courses and I have yet to use trig sub outside of Calc 2. There is almost always a better way to change the integral.

>>10524518
Dunno'.
It's the basic course that all math/physics majors have to complete. I am at TU München, but a quick look at https://www2.math.ethz.ch/education/bachelor/lectures/hs2013/math/analysis1.html
shows ETH Zürich has about the same syllabus, so I guess that's just normal in Europe.

>>10524506
>limes
If I'm not differentiating a lemon I don't want anything to do with the course

>>10517413
It must be sad and frustrating when you get filtered by a course.
Too bad I don't know that feeling :)

>>10524550
kek

>>10517417
lol wait until you take algorithm design, thats where all the cs bigbrains are at

>>10517787
My calc 1 had epsilon delta, riemann integration, basic differentiation and integration rules, related rates, mean and intermediate value theorems. Calc 2 had u sub, partial fractions, infinite series, convergence, convergence tests, L'Hopitals rule, change of coordinates, integration for area and volumes. Calc 3 was vector spaces and vector fields, partial derivatives, double and triple integrals, vector valued functions. Geometry of euclidean space. Inner product spaces. Div, grad, curl. Applications to heat transfer and electromagnetism. Integration of 2-dimensional algebraic curves (Iirc this was the hardest part).

Calc 2 and especially 3 were the hardest math classes I took, and this was at a high school. Now I have a BA in math from a decent university (UMD) and Ive taken study like set theory, real analysis, abstract algebra, logics, probability, graph theory etc. Set theory was pretty hard, especially all the stuff about non-standard models, universes of sets, and the distinction between the formal/object language and the interpretation. Topology was also pretty hard since O took it before real analysis and some of the definitions (e.g. compactness) were completely devoided of intuitive content when I forst learned it, but none of that was nearly as hard as my community college calc 3 class. The professor was actually this dude who had a reputation of being the hardest professor ever. If i remember correctly, we covere the whole syllabus in the first 8 weeks of class and spend the last 5 weeks or something doing a ton of extra shit thats usually covered in shit like "advanced calculus" or "vector calulus". Dudes name was Dr. Nilotpol Ghosh btw. He was quite infamous on ratemyprofessor back when I took him. Tbh though the class hurt my GPA but was probably the most intense learning experience I had as an undergrad.

>>10524689
*at community college, not high school

>>10520184

>>10524550
Yeah I like to come to anonymous internet forums and remind everyone I post with that I have never struggled in an academic setting, and I disparage and ridicule anyone who admits to ever having struggled with a chapter or do well in a class. Because I have 160 IQ, a 10 inch dick, a supermodel girlfriend, and a 12 million dollar trust fund. I had a PhD two years after graduating high school. I'm not arrogant though, I know I'm only slightly above average for the typical /sci/ poster.

>>10520629
Yeah it's probably that. I hate these god-damned gen-eds I have to take. Wasting time I could be using for MATH.

>>10522920
It's just algebra with limits

>>10524919
Did someone touch a sensitive spot there, buddy?

Calc 2 is the only class I'm taking this summer, how hard could it really be?

>>10525254
math classes are easier than they have ever been. there hundreds upon hundreds of hours of free tutorials on youtube alone. I was just get a heads up on the series part if I were you as that seems to be what trips most people up

>>10520956
According to my course catalogue, it is normally taken in the 2nd semester of the first year, but this can vary depending on your level of math proficiency. If you've already taken AP Calc in high school, for example, you may be able to take it in the first semester or perhaps even skip it altogether and go straight into Calc III. If you need to take some remedial courses like Trig or Pre-Calc, you might not even take it in the first year.

>>10521960
Never, ever, EVER, rely on the schools or teachers to teach you anything. Do whatever you have to do to facilitate your own learning process yourself. If that means studying it online, reading books, going to classes, or whatever else, do it. I can promise you, in my own experience, if I had just attended math classes expecting to receive all the necessary education for passing said classes, I would have failed every one. Teachers are not your friends. They are lazy, incompetent, idiots. I'm warning you, man. Educate yourself.

>>10526983
Personal experience. It's a good example of how everything can go wrong but it's no the typical case, as I know.

>>10525225
There’s unironically nothing wrong with this, increasing gravity when designing for loads would be a built-in safety factor

>>10524444
you really should just be doing hours of "homework" out of the book anyway for experience. time on task, friend

>>10527140
or you could come up with an actual safety co-efficient instead of using a false value for gravity?

Taking calc 1 and calc 2 this summer. How fucked am I?
Took the businessfag calc 121 but that was at a community college. These summer classes are at a state uni

>>10525225
I'm about to graduate with a BS in Civil Engineering, and I'd agree it's one of the easier engineering majors.

That would explain the large female-to-male ratio when compared to other engineering majors like Aerospace or Mechanical.

With that said, regardless of the field of study a good engineer is a good problem solver and critical thinker.

>>10527399
Don't know about others, but we use 9.81 m/s^2 as g when dealing in metric and 32.2 ft/s^2 when dealing in imperial units.

We also have other safety factors when dealing with beams and columns such a the safety factor phi based on ductility of the material as well as factored loads that take into account the largest contributing factor of dead loads, live loads, seismic, snow, rain, etc.

I'd just like to interject for a moment. What you're referring to as calculus, is in fact, real analysis, or as I've recently taken to calling it, [math]\left( \mathbf R,\, +,\, \times,\, \leqslant,\, \left| \cdot \right|,\, \tau \,=\, \left\{ A \,\subset\, \mathbf R \mid \forall x\,\in\, A,\, \exists \varepsilon \,>\, 0,\, \left] x \,-\, \varepsilon,\, x \,+\, \varepsilon\right[ \,\subset\, A \right\},\, \bigcap_{\begin{array}{c} A \,\sigma \text{-algebra of}\, \mathbf R \\ \tau \,\subset\, A \end{array}} A,\, \ell \right)[/math]-analysis. Calculus is not a branch of mathematics unto itself, but rather another application of a fully functioning analysis made useful by topology, measure theory and vital [math]\mathbf R[/math]-related properties comprising a full number field as defined by pure mathematics.

Many mathematics students and professors use applications of real analysis every day, without realizing it. Through a peculiar turn of events, the application of real analysis which is widely used today is often called "Calculus", and many of its users are not aware that it is merely a part of real analysis, developed by the Nicolas Bourbaki group.

There really is a calculus, and these people are using it, but it is just a part of the field they use. Calculus is the computation process: the set of rules and formulae that allow the mathematical mind to derive numerical formulae from other numerical formulae. The computation process is an essential part of a branch of mathematics, but useless by itself; it can only function in the context of a complete number field. Calculus is normally used in combination with the real number field, its topology and its measured space: the whole system is basically real numbers with analytical methods and properties added, or real analysis. All the so-called calculus problems are really problems of real analysis.

Another monkey here. We usually have 4 calcs, but Calc 4 is essentially babby complex analysis, Fourier, Laplace and babby differential equations.
It makes sense since engineers usually just have Calc 1 to 4 and Linear Algebra as maths in the curriculum.
