/sci/ - Science & Math

I refuse to help anyone who watches the office, or uses memes related to it. It's a dry show and a sign that you are an NPC. I never laugh when it's on anywhere. I see people chucking at it. Not me.

>>10449285
If it's anything like my calc 2 class was, the prof will curve the shit out of the class and you'll get at least a B.

>>10449432
I haven't talked to him, but the chair told me none of the classes at this school are curved. Whether or not that's actually true is a different story, but I've heard it's not unusual for a lot of people to fail the math/science classes here. I'm not sure if I should stay in and risk failing the class. I got a midterm warning because of the grade from the first test.

>>10449456
Talk to your professor, ask them what they think your chances of being able to pass are, and how much you could realistically improve. Then decide from there.

>>10449285
Boyo I used to flunk math classes. I got an honest 20% on a test once. And it really didn't get better from there until I made a full time effort to improving.
>but this time the HW was way harder than I could do on my own.
Then figure it out. You can go to tutors all you want and have them walk you through it but it won't give you any lightbulb moments, just my opinion.
https://www.khanacademy.org/math/calculus-2
Do it all. Get books on it. Watch videos on it. Read the whole textbook. Analyze completed problems. Whatever it takes. You'll know your in a good spot when you can go through practice problems knowing exactly what to do for them.
>>10449499
If he scored a 53% he can still pass the class with a decent grade. I had a calc class where I scored a 50 something on the first test. Second test an 85 ish, class ended with a B+. It can be done but you have to really want it.

>>10449499
Yeah I was gonna do that yesterday, but I kinda feel like it's a pointless question because the obvious answer is going to be "score as high as possible". The thing that bothers me is that this was the first test, where i studies like crazy and still failed. And I know the class will only get harder.

Here's the thing, it's not just a matter of passing the class. I am legitimately sick of struggling like this in math. It feels like I have to expand a lot of effort and I still never get As or B+s. If this were the final math class I needed to take than yeah I wouldn't care, but it's not.
>>10449594
That's part of the issue, if I'm being honest here. I'm not even sure if I want to do anymore right now. Part of me doesn't think I can do it either, as far as passing this class.

>>10449293
Wow you're so intelligent. What kind of humor entertainment do you consume? Funny operas?

>>10449649
When you get your test back, go through the problems that were wrong and look at why they were wrong. Then do it over again. Change the numbers and see if it comes out right, if it doesn't, go back and do the original again. Repeat until you can get all the missed problems right with different numbers. The point is develop an understanding of the material.
There are a lot of calculators online that can show you if your solutions are correct or not. Just google em
>I can't do it
You definitely can.

>>10449660
First of all, I do not "consume". But to answer your question, Some works in literature have succeeded in making me laugh, such as "The Life and Opinions of Tristram Shandy, Gentleman".

>>10449285
Watch professor chad

>>10449285


Wtf were you doing...? Srs question

hardest topic in calc 2 is:

first exam: various integrals u have to solve using different methods like parts, u-sub, trig sub

second exam: various series u have to solve using different methods like p-server,comparison test, root, ratio etc

third exam: easiest one, just compute the taylor series and power series

>>10449664
How's it being a virgin?

I really dont get what you're even talking about here. Like, calculus problems are just blindly following a few rules. You can't possibly be bad at them unless you actively try to be bad at them.
Stop trying to be bad at them and sitting there confused, get a fucking list of techniques next to you, and work problems using the list until you dont need to look at the list anymore.
If you're looking for more understanding than that, you'll just have to fucking wait until you can do well on your tests. This stuff is purely mechanical.

>>10449660
>funny operas
>implying i enjoy art
my entertainment is hartshorne

I got a B in Calc 1 and just started doing all the homework in Calc 2. Got a 91 on the first exam

>>10449662
>>10449672
Yeah I'm aware that I can use desmos and symbolab, and while it is fairly helpful it's nowhere near as effective as a in-person tutor for me. I feel like that's what hurting me the most right now.

>Wtf were you doing...?
Do you mean in the class or what I did personally? I'm not all that terrible at the techniques for integrals, though not great, but I lost 25 points on the test from two volumes and one tank problem. Those are the ones that are giving me the most issues out of everything right now.
>>10449667
I wish this guy was my professor, he makes the material so much easier to understand

>>10449686
just consider on this exam you got a 53% on...

someone in ur class got an A.

How could you let the professor outplay you lol? He made the exam to trick all of his students and lold as he got you with the 53% man

>>10449686
Are you drawing a picture of what you're trying to solve? That's the most useful thing for those volume/tank ones, at least for me.

>>10449686
volume problems? Like 'heres an y=f(x) and rotaed about line x=3 or about x-axis" etc

thats easy as fuck you just follow the formula and integrate with respect to Y or X

tank problems? Like "salt is filled etc find how much salt at time t"

same shit its a formula

>>10449649
Yeah, calc 2 is going to get a lot harder, and then a little easier near the end. I still have nightmares about sequences and series.
But honestly, higher level math classes are arguably easier than calc 2. Or so I've heard. I've only gone up to calc 3, and calc 3 is definitely much easier. So just muddle your way through this class and hang in there. Calc 2 is a right of passage.

>>10449700
>I still have nightmares about sequences and series.
Lol, must suck being a brainlet

>>10449689
That's what makes me feel worse about it. I don't understand how I'm this bad at Calc 2 even though I studied as much as I did. It's more annoying and depressing at the same time. But I feel like I'm on an island almost, like I'm not getting it and there's nothing I can really do.
>>10449690
For the volumes problems yeah I always draw it, but I still end up getting them wrong either by not plugging in correctly or messing something up during the integration. But on the exam I missed it completely and lost almost all of the points. The tank I still cannot do at all.
>>10449694
Yeah I dunno what it is, my brain cannot wrap around those problems. Some of them I just shut down and don't know what to do. And when I went to tutoring the guy started getting annoyed with me because I wasn't getting it.

>>10449700
Am I the only one who actually enjoyed series and sequences? Tbh after finishing up my discrete maths class and learning about induction it makes the sequences and series stuff very trivial.

>>10449700
Also I have heard that if you can pass Calc 2, you can pretty much pass any math class after that, but I'm not sure how accurate that really is

>>10449717
Its not true for anything past linear algebra lol.

>>10449285
you probably never figured out how to solve problems "your" way. most people have slightly different ways of thinking, if you only solved it the way the teacher showed it may not be clicking as well. i'm not talking about huge difference, more like preferences

>>10449721
I didn't think so either lol, that's why I want to do well in this class now so it doesn't end up hurting me down the line.

>>10449711
I think I just had a bad professor. I remember getting a 65% on that exam, and that grade was in the top 20% of the class...

>>10449727
Your professor is not the problem, there is a set standard that the professor has to test you on, nothing more nothing less. If you fail to come to at least a 70% mastery of the material over a given amount of time that's on you. There have been thousands of people in your shoes who have passed calculus 2 with no problems. I personally got over 100% in that class, if your professor is not doing it for you do what I did and watch professor leonard or use any other online resource (different book, youtuber ect...) so that you meet those educational standards.

>>10449727

I took calc 2 in hs when i was 17 (calc bc)

the professor was brilliant beyond words

our only grades was exams and quizzes

he said: 'the homework will help you but i wont grade you on it'

every exam was questions from old AP exams

ill admit I got 70% on first couple of quizzes and a 50% on the first exam

got a 5 on the AP exam which let me skip calc 2 str8 into calc 3 and differential equations
(which I would say is for sure the toughest undergrad course for engineers, tougher than linear algebra.)

>>10449729
I ended up with an A in the class

I did well on everything else. Got my shit together for the final and got 100 on it. So I'm sorry if screwing up a single exam means I'm retarded

>>10449735
I fail to see the problem then, your professor was reasonable enough to not count a bad exam against you and you got an A.

>>10449739
I think the real problem is that I'm a perfectionist and can't let this stuff go.

Point is, calc 2 is hard but doable. If you can get through it, you can probably handle upper level math classes.

>>10449746
Honestly, you will find that you can get a undergrad degree in literally anything, your IQ is not a determinant of what you can and cannot do as much as /sci/ or /pol/ wants you to believe. The main difference between someone who has a degree in math and someone who does not is really their work ethic. Idk about grad school though, that's another thing entirely.

>>10449675
This is the only good answer here. You go through a list of proven problem solving techniques and then try to solve calculus problems. They're just regular problems, but the scope is the world of 'Calc 2' whatever that is. Get Terrence Tao's problem solving book from libgen.io or buy it, or any math olympiad strategy book. You can also test your own understanding by using the so-called Feynman method. After you do a chapter, or from your notes, summarize it like you are explaining to a child. If at anytime you get tripped up or repeat yourself then go back to the material or find supplementary material until you can explain it effortlessly. This method especially helps when you're doing some crazy abstract shit, talking through it and teaching your invisible class of imaginary math students.

>>10449772
Interest in the subject matter is important too. I could've easily majored in math, but it was too abstract for me to really care about. I'm much more interested in biochemistry and computer science, so I put more effort into those than I ever did with math.

>>10449816
Yeah, obviously that goes without saying. You won't do well in your major unless you are passionate about it. Although, I got very interested in math as a CS major after taking my discrete maths class.

>>10449285
You have to memorize every derivative and anti derivative, every technique and when to use it, every test for convergence, and every taylor's series expansion. Calc is literally a brainlet filter. If you are incapable of pouring knowledge into the well that is your brain, try another discipline. Perhaps literature is more your style?

>>10449664

>>10449293
based

Calc 2 is piss easy.
>>10449594
This guy is right, listen to him.

>>10449700
Yeah calculus 2 is a fucking bitch honestly. I've taken quite a few upper level math courses and have found them way easier despite the fact that they require you to use everything you learned in calculus 2.

Honestly I don't know why that class was so hard, looking back I realize how easy it was but it seemed like the hardest shit ever. Fuck trig sub though, that shit blows.

>>10449711
I scored the highest in the class on the sequences and series exam whereas most people good wrecked, but did mediocre or straight up got JUSTed on the others. Luckily there were a lot of biology majors in the class so I still got by with a B due to the curve.

>>10449734
I will never understand why people make posts like this. Do you want us to all clap over how "smart" you are?

>>10451960
To be honest you are on a Mongolian basket weaving imageforum

bump

>>10453109
Careful.

>>10449285
Stop being stupid and actually bother to learn the theorems
Fubini’s theorem, why you use the jacobian determinant when changing variables, etc

>>10449293
That’s a very ‘The Office like’ reaction.
