Differentiation
Stationary Points
At a stationary the line has a gradient of 0
We differentiate to find the gradient
So when:
dy = 0 then there is a stationary point
dx
To find the stationary point put the differential equal to 0 and state why
We use the second differential to find out whether it is a maximum or minimum turning point
