Math2.org Math Tables: Integral sin, cos, sec^2, csc cot, sec tan, csc^2
1. Proofs For each of these, we simply use the Fundamental of Calculus, because we know their corresponding derivatives. cos(x) = sin(x), cos(x) dx = sin(x) + c-sin(x) = cos(x), sin(x) dx = -cos(x) + c sec ^2 (x) = tan(x), sec ^2 (x) dx = tan(x) + c-csc(x...
