1. ## Help with trig

Hey can I leech some help? From the Cambridge 2U book (4H, 10-e)

Find the area bound between y=sinx and the x axis, from x=−5pi/6 to x=7pi/6

Ans: 4 units^2

I'll give a hint - try sketch the y = sinx graph in that domain and remember to either minus the negative areas (to make it positive) or absolute value negative areas.

Note that the area bounded by the sine wave between $-\pi,\,\,-{5\pi}/{6}$ is the same as the area bounded between $\pi,\,\,{7\pi}/{6}$.
