Brainlet. Get out of my higher education REEEEEEEEEEE

If your struggling with the mechanics of it, watch Patrickjmt videos on YouTube on the stuff you need help with

Also do all of your homework. Change the numbers around. Change your trig functions from sin to cos or something. Test yourself. Get the pattern of finding a derivative.

Understanding the mechanics of it will get you far enough to pass the class. That's all. If you want to ace it, you're going to have to read your textbook and the books that the other guy above recommended.

Repetition, OP.

Take your time.

Patience.

I figured I write this in this thread, cause it's somehow related

Ok, so it will be my first time taking theoretical physics next semester. I'm at university for quite some time now and I've succeeded in the first four analysis courses. Also I took experimental physics (with success, although with massive problems, because never attended class). What can I expect from a real physics class? Any advices?

Post your syllabi. I have no idea what you're talking about.

Never got what this meant, what is it and where does it come from?

>>7909318
A movie, invasion of the body snatchers.

Clones made from people while they slept dominated a small town, and screamed when they find humans by knowing they had feelings by talking to them.

/r9k/ took from there.

>>7909100
four classes in analysis? what, introductory real analysis, analysis on manifolds, measure theory, complex analysis?

or do you mean calculus

[eqn]
\begin{align}
\int ax^n \; dx &= \frac{ax^{n+1}}{n+1} + C \\
\int \frac{1}{x} \; dx &= \ln{|x|} + C \\
\frac{d}{dx} ax^n &= (n)ax^{n-1} \\
\frac{d}{dx} \frac{a}{b} &= \frac{b(a)' - a(b)'}{b^2} \\
\frac{dy}{dx} &= \frac{dy}{du} \frac{du}{dx}
\end{align}
[/eqn]
Now go away, you can now survive Calc I and Calc II.

Calculus is one new concept. you don't suck at calculus, you suck at algebra and trig.

>>7908955
Are you me? I suck at calculus but this is partially because my teacher sucks too and I also suck at trigonometry.
What do?

>>7909881
Practice trigonometry. It sounds useless but becomes super useful in calculus whenever you want to do trig. sub. It also helps you understand [and prove] why stuff like [math]\frac{d}{dx} \sec{x} = \sec{x} \cdot \tan{x}[/math]

>>7909901
And what about non-trig calculus? We have finished differential calculus in class and I am the only one that does not know shit.

>>7909918
In that case, the best thing would be improving on algebra. Sounds dumb, but really if your algebra skills are flawed in the slightest, there will be that one step you may fuck up on and then you check if your answer is correct by differentating it and wonder why you wound up with a derivative that's nowhere near equivalent to the integrand. Besides algebra, keeping track on where you are also helps, obviously. Too bad the best example I can think of for this is doing trig. sub on a fraction with a square root on the denominator, lose track where you are and everything just becomes a giant cesspool of numbers and functions.

>>7909933
this. the big jump in calculus is that the teacher is flying through or straight up skipping loads of algebraic steps because you are expected to know all that shit already and it should be obvious.

>>7909901
What are some good books on trigonometry?

>>7909830
Thanks for the explanation anon!
Worth watching?

>>7911025
I don't know, they call it a classic nowadays.

Give it a try. They say the book is better.

>>7911039
Oh excuse me, watch the one from 1978.

Hey can anyone help a bro out? While solving this integral I factored out the 8 and ended up with the wrong answer. U sub gives the right answer. Can anyone explain please? Ty

>>7911044
You just plug in du=8dx into the top left one. Also always write your dx for your integrals.

>>7911051
You just didn't*

>>7911053
Thanks for the input, and yeah I'm pretty forgetful when it comes to writing the dx. But is that the only way to do it? I mean, isn't there a way to get the answer by factoring out the 8?

>>7911061
It doesn't matter that the 8 is factored out or not, when you plug in du = dx/8 it cancels it out anyway. You just skipped straight to dx = du without taking into account what the derivative of u was equal to.

>>7911066
dx = du/8 ****** don't drink and derive

>>7910999
Now, I'm not saying it's a good one, but I used Stewart's "Algebra and Trigonometry" in my Trigonometry course and it was awesome. The colored and labeled diagrams really helped my understanding of the material.

Thanks so much

I honestly do not know any good books for trigonometry. When I took trigonometry, I depended on those horribly written pure-HTML sites that gave you the most painful reading experience ever. In the end it was pretty worth it because seeing explanations from a perspective different than the teacher's was helpful. However, I can offer good books if you want to try prcalculus and/or calculus I and II.

Precalculus with Limits 2nd Edition (Ron Larson)
Calculus: 9th Edition (Varberg, Purcell, Rigdon)
Single Variable Calculus: Concepts and Contexts 4th edition (James Stewart)
Mathematics for Engineers II: Calculus and Linear Algebra (Gerd Baumann)

The precalc book is self-explanatory, I've tried it. It's 12 chapters long and the first 10 chapters I are just review over algebra and trigonometry. It started with basic algebra I stuff like distance formula, polynomials, factoring, etc., Did review over trigonometry, and then suddenly go back into algebra with inequalities and shit. Then for some reason also introduces very basic matrices. And in the last chapter it finally gets into limits.

Calculus: 9th edition is more learning towards HS-calculus, so you should not expect anything hard from it, but you should also not expect anything new assuming you already know Calc I and/or II.

Single Variable Calculus 4th edition is also yet another AP calc book, it's okay but I definitely do not recommend self-learning Calc I with it. It'd most likely be best to use as a supplementary book.

Mathematics for Engineers II is primarily just Calc II and III stuff along with introductionary linear algebra. If you're not that familiar with partial derivatives, do not try going through this entire book, the examples are pretty poor.

>>7911329
Forgot to mention this...All the books I posted were purposefully selected based on the assumption that you're just going to practice and get refreshment algebra II and basic calculus. If you do not know anything about algebra II or calculus, these books do not teach it very well unless you're able to actually focus and have a slight background on the topic, but the problems they give do serve as good practice.
