Oh...and if you want to go to calc II and beyond, not only do you need trig identities, but the techniques and concepts learned in implicit differentiation. Implicit differentiation is very important if you want to grasp concepts like partial derivatives.

Not that I'd know, I've only passed calculus 1.

>>6187896
Where I went to school, we had "calculus and analytic geometry I, II, and III" The first class of the three, the only one I took, started with limits, then epsilon-delta, then basic derivation rules(power, product, quotient, chain, combinatons thereof which were all just limit rules rehashed), implicit differentiation, went on to related rates, second derivitaves and optimization, antidifferation, simple indefinite integration, simple definate integration, logiarithmic differentiation, then solids of revolution and arc-length stuff.

From what I heard, other schools don't get into integration at all until calc II. Yet other schools have multiple levels of calc depending on major. "easier" calc lines include "calculus for business" and "calculus for the life sciences"(the latter is a lot of logiarithmic and exponential problems).

I am drunken, don't get me wrong, but getting high is also a good idea, so I can work on my dessertation about lie algebra, meaning I lie to you about algebra. Jack! You have to beLIEve me!

All joking aside, I did after 10 years in community college pass calc 1 with a "B," so I am a reliable source for the person anticipating calc 1.

Second-derivatives in calc 1 are as easy as first derivatives*. The second line of your post makes even less sense than wholesale cock-gobbling.

* Finding them is easy. Using them in optimization problems involves a bit more creativity.

>>6187866
Not only did you say what I've already said, but you've spoken it like a bloviating consultant getting paid $60 an hour to enumerate common sense. Who do you work for, and where can I sign up?

>>6187859
Besides the vertical line thing and the taking of the cocks in my mouth, are the rest of my points not cogent and useful?

When most calc 1 professors go into antidifferentiation, they simply assume that students know how to do it because it is the opposite of differentiation, though it is not readily apparent to some students. That's why I listed my antidifferentiation shortcut. And my tip for visualizing sqrt(x) as x^(1/2) etc. is something not mentioned unless you're in the know.

I want to take both of your cocks in my mouth at once, so that your juices mix inside me, and let it dribble down my chin as I lecture you about not making Professor Math Whiz look stupid.

Then I will eat a can of alphabet soup and take a math whiz all over the both of you.

Because most textbooks and professors suck if not entirely omit visual aids.

>>6187800
Again, Professor Pedantic, you are correct.

>>6187796
And...get this...e is not only its own derivative, but its own integral as well! Mind = fucking blown!

>>6187782
I took the "hard" calculus 1, "calculus and analytic geometry," and the trig problems were pretty easy, because trig derivatives and antiderivatives are mostly simple. You get more complicated stuff at the end and In calc II, but if you're one of those Calc 1-only majors you can have a piss-poor understanding of trig identities and do well.

The vertical line marking the transition point was what I was talking about. Sorry for the confusion, its been a few years. You win. I lose and shmear my shit all over my chest. Hooah!

>>6187757
>>6187765
You know what I meant. I may have given the wrong formula, but I was basically saying that I lost points for using the quick power rule rather than all those tedious manual calculations that increase the risk of error.

>>6187773
Unless you're going into hard fucking science, you can disregard complex numbers, as they are often not mentioned at all in a calc I class.

>>6187770
Optimization problems are one of the coolest applications of calculus, though they tend to give some students trouble because the problems depend on sketching a diagram kinda like problems in Physics class. Still, one of the few moments where I was like, "Math, fuck yeah!"

Solids of revolution are just an integral's evaluation multiplied by 2*pi and arc-length problems are plug-and-chug.

>>6187730
Yes, you're right. My rationale for saying that is if you watch an animation where a tangent line follows the function curve, it is vertical where the second derivative equals zero, even though the line is only an artifact of the visualization and not technically a "tangent."

Using the rules for differentiation and antidifferentiation I showed you above, you can see that the a circle's circumference is a derivative of its area, and that a sphere's surface area is a derivative of its volume.

>>6187724
If you are ahead with your calculus techniques, be sure to ask your professor if they are cool with letting you use more advanced techniques to take shortcuts early on.

My professor was a fucking dick and took away points because I used the chain rule instead of evaluating f(x+h)-f(x)/h.

>>6187715
In my opinion, the epsilon-delta definition detracts from understanding and should be saved for Calc II. So when you hear people talk about epsilon-delta bullshit, the short version is that at a point in the function, the derivative coming from the left may be different than the one coming from the right, or one or both may not exist.

Also, namefagging.

Look at the bottom-two sine waves superimposed on each other -- It is a fundamental concept of physics that the voltage(Q) waveform leads the current waveform at 90 degrees.

Now - when you deal with a complex reactance, like how ultrasound operation effects the internal impedance, the voltage waveform lags the current waveform due to multiplication with the imaginary unit negating the properties of voltage and current.

Any more questions? More slides would he helpful in explaining as well.

Having staggered into this forum, I see that lots of people say they learn integrals in calc II.

Where I live, we call undergrad calc I "calculus and analytic geometry," and the first semester is at once limits, differentiation, and integration; bustin' implicit differentiation, optimization, solids of revolution, and logiarithmic differentiation among other topics. Our calc II deals with sequences and series, improper integrals, and partial differentiation.

Assuming I passed both(which I didn't), did I learn more than you did when you took calc I? calc II? Post your schools and how they do it.

Yeah, it's called "having a life" in high school, then having to go to school while working for a living. I wasn't a scholarship weenie and don't have a rich family.

>>4887399
I'm an almost lifelong resident, and I've been around.

Well, then what the hell am I supposed to do to get my bachelor's degree?!
>in before University of Phoenix

Hey, /sci/, I have come to you for advice -

After 10 years in community college, I will finally be ready for transfer to a CSU school (California State University).

Problem is, I'm mostly white and have always identified myself as such. Is there any way I can leverage my 1/8th Native American or 1/8th Hispanic blood taint to jump the admissions line? My GPA is 3.4 (with a SHITLOAD of withdrawals). What SAT score would I need for a guaranteed admission? Stories welcome.

Actual women, if you listenin' -

Get real - men stare at your tits because you are not giving them a good reason to engage your mind. You have no personality. You are either a feminine version of an awkward male neckbeard, or some 7/10 who believes that men should do all of the carrying of the conversation just because every drunken limpdick at the party notices that you have a vagina between your legs and asks for your number.

Try being interesting and considering some kinds of attention more fulfilling than others. Then maybe, just maybe, men will feel compelled to look into eyes and engage your soul rather than see you as some vapid meatbag attention whore.

I have a question upon a question. Calc(and analytic geometry) II is considered a 'weedout' course for those wishing to attain a bachelor's degree in a science greater than biology. Calc(etc...) here it is improper integrals, sequences and series, and rudimentary partial derivatives.

Do I stand a chance, considering 2 hours per day of study?
