Firstly we need to rearrange this equation so that it contains only one trigonometric function of x (i.e. tanx, cosx or sinx) which will make it much easier to solve.

We can do this in th...

We can imagine our function as a curve. We have x values on the x axis and f(x) values on the y axis of our graph. 

The question is essentially asking us to find the area between the curv...
