Derivatives of sin x, cos x, tan x, e^x and ln x | Product and quotient rules | Khan Academy Here is a proof of the derivative of sin x. d/dx (sin x) = lim h→ 0 (1/h) [sin(x+h) - sin (x) ] _by definition of derivative_. _Using the angle sum identity: sin(x+h) = sin(h) cos(x) + cos(h) sin(x)_ d/dx(sin x) = lim h→ 0 (1/h) { sin(h) cos(x)+cos(h) sin

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
