The easiest thing to do is to look at what is in the name. For integration you have `in`, which corresponds to an `increase` in power. Whereas with differenentiation you have `d` for decrease in power. Then ...

Differentiate both equations given with respect to t. dx/dt = -2sin(t) dy/dt = -6sin(2t) dy/dx = (dy/dt) / (dx/dt) Sub your values in to get dy/dx = (3sin(2t))/sin(t)

First of all, read the question twice. Then, using a highlighter, highlight the key words of the question (one to four terms which are at the core of the question. E.g. " Analyse the success of Alexande...

The derivative of a function f(x) is a measure of how the function f changes as its variable x changes. You have already met an example of derivatives: the gradient, m , measuring the rate of change of f(x) ...
