# Derivatives of Trig Functions - Expii

We compute the derivatives of trig functions. For example, the derivative of sin(x) is cos(x) while the derivative of cos(x) is -sin(x), which can be shown using the limit definition. From these facts, you can then compute the derivatives of tan(x), sec(x), csc(x), and cot(x) using the product and quotient rules.
