# Math Help - Find the area..

1. ## Find the area..

Find the area between and over the interval . Sketch the curves if necessary.

2. You will need to find if they intersect on that interval first.

I.e. solve $6\sin x = 7\cos x$

Here's a hint $\frac{\sin x }{\cos x} = \tan x$

ok so i'd get 6/7tanx.. what do i do with that?

You mean $\tan x = \frac{7}{6}$

Solve for $x$ then, is this that value on $[0,\pi]$ ?

If so you will have to break up the integral to avoid any cancellations between positive and negative regions.
