Seen, later if no one has done them yet

I left the last 2 qns for you ;)

Ok, writing them up later

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).

For this chapter still got equations of tangent and normal to a curve
Rates of change

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

This chapter is huge

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