Intermediate Mathematics - Stationary points

Stationary points

To find the stationary points differentiate

depending on the notation you are using.

There are a number of methods for finding the nature of a stationary
point. Two methods are described here. In these you can either use function
values to the left and right of the stationary point or consider the sign
of the derivative to the left and right of the stationary point. The second
method is often called the Sign Test. Either method is fine to use.
