What's the best way to cram my brain for a couple proctored exams due by Friday?
Trig:
Section 7.1 The Graphs of Sine and Cosine
Section 7.2 More on the Graphs of Sine & Cosine; Phase Shifts
Section 7.3 Graphs of the Tangent, Cotangent, Secant, and Cosecant Functions
Section 7.4 Inverse Trigonometric Functions I
Section 7.5 Inverse Trigonometric Functions II
Section 8.1 Trigonometric Identities
Pre-cal:
4.1 Quadratic Functions
4.2 Applications of Quadratic Functions
4.3 Graphs of Polynomial Functions
4.4 Synthetic Division, The Remainder & Factor Thm
4.5 Zeros of Polynomials, The Fundamental Theorem
4.6 Rational Functions & Their Graphs
4.7 Variation
I'm 29. Make fun of me all you want. Trig in particular is a bit difficult. I don't know why it's considered even a lower-level math than pre-cal. Pre-cal is much easier.
1. close 4chan
2. open book

No book unfortunately, rather an e-book built into a shitty program/website...
>>8153831
Khan Academy.

This, he's actually really good for pleb shit like early trig and pre-cal
You learn the first section in one hour, and the second one in another hour.
Trig is not very difficult. It seems that way because you need to memorize identities
>>8153831
read as much as you wan't, to learn math at that level you need practice, solve as many problems as you can
>>8153922
>calling the ABC's of math pleb shit
>>8154117
> transcendental functions
> not for plebs
>>8153831
get the fuck off our board

Do practice problems from the book, lots of them. Do them until you're sick then do them some more. Since it is lower level math, I am going to guess there will be practice problems similar if not straight from the book so it'll be great practice. Plus being exposed to several problems is a great way of understanding the concepts behind them.

You can remember all of the trig by remembering the three special triangles, and you can just sub in the sides represented by the function to solve the identities.
As long as you can figure out when x=0, and have an idea of where to set x=0 if you are creating a function, you are done precalc.
