Hi,

Please could someone help with the following problem.

(a) Sketch the curve for y = sin(x) between x = 0 and x = 2pi,

(b) Then find the total area enclosed by the curve y = sin x and the X axis between

x = 0 and x = 1.7pi

I've sketched the curve but I'm struggling with the second part, please see below.

Next I integrated the area above the X axis using the limits.

Then I integrated the area below the X axis using the limits.

When I subtract area1 from area2 i seem to be getting an answer of 0, which doesn't seem right.

Any help appreciated.
