# Maxima and Minima with Trigonometric Functions

Home > Differentiation Periodic motions can be modelled by a trigonometric equation. By differentiating these functions we are then able to solve problems relating to maxima (maximums) and minima (minimums). Remember that the following steps are used when solving a maximum or minimum problem. Step 1: Find $f'(x)$ to obtain the gratest function. Step 2: [...]
