# Maths (C2) watch

1. 1) Trigonometrical Identities.. How do I know when the range has changed?

2) How do I intergrate and then calculate the area under a curve?

Thanks
2. 1) Draw out the trig curves
2) Integrate the curve equation with respect to whichever axis bounds it. Then add limits as the two coordinates on that axis bounding it. Plug each of these numbers into your integral and subtract the second from the first.

Good luck
