Trig identities can help to evaluate things like, say, sin(15) by using the identity for sin(A-B) with A=45° and B=30°, giving an exact value.
Polynomials and poly-type functions: –General tip: try factoring, then cancel common factors. –Large arguments: the largest-degree term dominates, so divide and multiply by that term. Trig and inverse trig functions: –General tip: know the graphs of all the trig and inverse trig functions,...
