too late to prepare would be about 20 minutes before the exam, depending on how fast you can read

A derivative is the graph of the slope.
A limit is the value that a function approaches as it gets closer to a number

What exactly is it you find difficult? You still haven't answered this question yet you're bitching because your fee-fees are hurt. And yes I am saying Calc 1 is easy, it's ridiculously easy as long as you study. You ARE studying right? Or are you busy with trap porn and vidya?

Like he said, he probably just has a weak trig understanding, which really fucks things up in early stages for people.
OP does have plenty of time to get that down, and there are a lot of resources out there for calc.
OP, check this out http://tutorial.math.lamar.edu/Classes/CalcI/CalcI.aspx
Go through all the trig stuff and try to remember the common graphs. Also like I said, there's plenty of resources for calc, just be specific with the google machine. Check out khan academy and what not, and above all, lose any ego you have.
The limits and derivatives should come to you pretty easily if you put enough work in.

[Anonymous No.10375945]

>>10375658
Try to get things into recall memory. Read the book until you think you understand it, then put it away. Try to solve a calculus problem without looking at the book. Even if an answer isn't coming for a long time, keep trying to remember or figure out the answer. If it gets absolutely impossible, you can check the book to get the thing that you're missing. The struggle will make that step easier to recall in the future. After doing this a few times, you should be solid on the processes.
After a while, you can do the math like you would do sudoku or crossword puzzles. It can be relaxing.

You have to study more, period. Either quit your job or work less hours if you're struggling this much. Calculus is not a class where you just show up twice a week, read a few paragraphs and examples and pass with a B+, you have to sit down and do problems. Calc 1 is literally just practicing limits and derivatives, that's it. You don't even need to memorize anything for Calc 1. For fuck sake, it's really not that hard.
>>10375624
You don't even need a strong trig background for Calc 1. As long as you can do algebra that's more than enough. Unless you have one of those asshole professors that likes to bombard every exam with trig problems, and even there if you know basic trig identities you'll be fine. I'm just sick of people bitching about Calc 1 being hard when its not. Almost all of these people think it's "hard" because they either don't study at all or can't do algebra for shit.

This. You pass it with an A. In burgerland you aren't even required to do proofs in calc.

Nigger i did complex analysis in my free time, studying for calc 3 has nothing to do with difficulty and everything to do with arbitrary memorization.

[Anonymous No.10376134]

>>10376029
There's nothing in real anal that requires 'arbitrary' memorization, you can come up with almost any proof that's realistically going to be on an exam just by attending lectures (and paying at least some attention, sometimes). It's the most intuitive undergrad course.
Arbitrary memorization is numerical methods, not real anal.

Either way, there's nothing to memorize arbitrarily. If you mean you have to "memorize" what curl means and what could possibly be hiding behind "spherical coordinates" and things like that, then perhaps but your definition of arbitrarily is very loose then.

This is the written part of the exam - computational part:
1. Compute
[eqn]\lim_{n\to\infty}{n}\bigg(\bigg(1+\frac{1}{n}\bigg)^n-e\bigg)[/eqn]
2. Determine convergence of
[eqn]\sum_{n=1}^{\infty}\frac{1}{n+1}\bigg(3+\frac{\log{n}}{n}\bigg)^nx^n[/eqn]
in terms of [math]x\in\mathbb{R},\,x\geq0[/math]
3. Compute
[eqn]\lim_{x\to0}\frac{2\sqrt{1+x}-3\sqrt[3]{1+x}+\cos{x}}{x^2}[/eqn]
4.
[eqn]f(x)=\begin{cases}
\exp{-\frac{1}{\sin^2{x}}},&x\in\mathbb{R}\setminus\{k\pi,k\in\mathbb{Z}\}\\0,&x\in\{k\pi, k\in\mathbb{Z}\}\\
\end{cases}[/eqn]
Let [math]\mathcal{D}(f)[/math] be the set of arguments for which[math]f(x),x\in\mathbb{R}[/math] is well-defined. Determine this set.
Find the subset of [math]\mathcal{D}(f)[/math] where [math]f[/math] is continuous.
Find limits in exteremes of domain and whether the function has asymptotes.
Find the subset of [math]\mathcal{D}(f)[/math] where [math]f'(x)[/math] exists and compute their values.
Find intervals and monotonicity.
Find all local and global extremes.
Determine range.
Find the subset of [math]\mathcal{D}(f)[/math] where [math]f''(x)[/math] exists and compute their values.
Find intervals of convexity and concavity.
Find all inflex points.
Sketch a graph.

This is the oral part:
Define derivative, limit point of sequence.
Prove the Archimedean property for real numbers.
Prove equivalence of Heine- and Cauchy-continuity.
Prove Rolle's theorem.
Prove d'Alembert's ratio criterion.
Prove Bolzano-Weierstrass theorem

we don't do calculus at uni, you only see calculus at written parts of exams
engineering unis usually leave out the oral exam and have more problems in their written exams, so it's effectively calculus

[Anonymous No.10376703]

Imagine being so anglo that you think there's any reason to differentiate analysis and calculus.
Imagine being so anglo that, instead of allowing talented individuals to take graduate courses, you allow them to take undergraduate courses instead of highschool courses - real "honor".

No, hence my remark >>10376026
>I see, it's one of those "lets make this class artificially harder than it actually is" courses
Oral exams are the standard here for mathematics. They don't make anything harder, quite the contrary - when you struggle on written exam, you're screwed, when you struggle on oral exam, the examiners usually give you a nudge.
If you want to know what artificially increasing difficulty is, you should try a semester in Russia. Zorich and pals will tear you a new one (or a dozen).
