hi

need to find area of graph

$\displaystyle y=(2sinx-1)(sinx+2)exp(\frac{2}{3}sinx)$

i have limits from previous question $\displaystyle \frac{\pi}{6}$ and $\displaystyle \frac{5\pi}{6}$. i know i need to intergate this but i just can not do it. i have been trying to answer these question since 8am, could really do with some help.

many thanks
