Kathy, next up are the three applications of differentiation (coordinate geometry, maxima minima and rates of change), followed by differentiation of trigo, exponential and logarithms. You must be able to do all the basic ones first before proceeding to trigo. That sums up the differentiation portion in a maths (except for the last chapter kinematics).

Equations of tangent and normal are simply no more than using the concept of dy/dx in your coordinate geometry

I estimate calculus to take up between 30 and 40 percent of your marks
