so is the curve all above the x-axis from x=1 to x=2?
Let's think about this. 1 is in between pi/4 and pi/3 2 is less than pi |dw:1387146930400:dw| But from pi/4 to pi cos isn't always positive, is it?
In fact it switches from positive to zero when we get to pi/2

you want to find the evaluate two integrals for this problem.
One will be from 1 to pi/2 the other will be from pi/2 to 2
take the absoluste value of the second integal because it will result in a negative number since it is all under the x-axis there
I will back later.
Alright. I got it thanks :D
