How do you find the coordinates of stationary points on a graph?
First differentiate the function: y = f(x) => dy/dx = f'(x)
Then set dy/dx = 0 and find the solutions. i.e. solve 0 = f'(x)
For each value of x that is a solution, substitute back into f(x) to get the y coordinates.
We now have the coordinates of the stationary points.
