Derivatives of Trigonometric Functions

The integral of sinx is closely intertwined with the antiderivative of sinx, which is -cosx. This relationship is illuminated by the chain rule and the power rule of differentiation.

Antiderivative

In calculus, an antiderivative is a function whose derivative is the original function. A way to think about antiderivatives is as the opposite of differentiation. If differentiation finds the slope of a function, then antidifferentiation finds the original function from its slope. In our case, the antiderivative of sinx is -cosx, which means that taking the derivative of -cosx yields sinx.
