I have a weak math foundation. I decided to start all over again, beginning at algebra. I am looking for something specific but I am not sure how it is called.
Our math professor always plays with equations and functions. He constantly simplifies equations or functions by rewriting them. But sometimes I have no clue what is going on. I hope you know what I mean by that.
Do you know if there is a cheatsheet that contains all rules that I can use to simplify or transform an expression, equation or function?
For example something like $x^2 + 1x -6 = (x - 2)(x + 3)$
Or if you do a derivation of sin, then you get cos.
So that I have all rules at one place.
Even something basic like $sqrt(4) = 2$ , $4 = 2^2 $
