    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

    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
