Trigonometric Derivatives

A guide to the derivatives of sine, cosine, tangent, and other trig functions.

Derivatives of trigonometric functions are essential for solving problems involving periodic motion or geometry. Basic formulas include d/dx(sin x) = cos x and d/dx(cos x) = -sin x. For complex functions, these are often combined with the Chain Rule.
