    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

    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.
