Pre-Calculus Skills
Vital skills you need to be successful in AP Calculus
Unit Circle - Navigating Radians
Learn how to easily identify each angle multiple of 30, 45, and 60 degrees in radians (pi/6, pi/4, & pi/3).
Unit Circle Coordinates & Trig Ratios
Learn how to mark the coordinates for each key angle on the Unit Circle, and use those to find the applicable Trig Ratios.
Inverse Trig Functions
Review the ins-and-outs of Inverse Trig Functions such as notation, what type of ‘answer’ are we trying to get, when to give multiple answers or just one, and what to do if the trig ratios look “scary”.
Logarithm Rules
Review the rules of logarithms and see a few examples of traps you don’t want to fall into!
Examples of Piecewise Functions
Simpler than they look, Piecewise Functions pop up quite a bit during AP Calculus.
Binomial Expansion
How do you expand something like (x+3)^10 without having to multiply the whole thing out?!
