Thank you

I give u good le

Stationary points —> dy/dx = 0, solve for the coordinates

Remember that dy/dx is gradient at a point, this sounds superficial but it’s important when doing the first derivative test to determine whether the stationary point is a minimum, a maximum or something called inflection.

Second derivative test is an alternative way, using an entirely different approach altogether.

All these will be seen in the next part of differentiation.

June: Maxima/minima,

First half of July: Differentiation for trigo, exponential and logarithm

Second half: revision, basic integration

August: Areas under graphs, integration of trigo and exponential, kinematics
