To evaluate this area correctly, divide the interval in two parts 0 to pi/2 and pi/2 to pi = [sinx]_0^(pi/2) + [sin x]_(pi/2)^(pi) The area above x axis would come to be +1 and that below x axis would come to be -1. Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. sin^2(x) + cos^2(x) = 1, The value of Cos pi= -1 and Sin pi=0.

The trick is to rewrite the $\\sin^2(x)$ in the second step as $1-\\cos^2(x)$. Then we get We also know the trig identity sin^2(x) + cos^2(x) = 1, so combining these we get the equation cos(2x) = 2cos^2(x) -1. Now we can rearrange this to give: cos^2(x) = (1+cos(2x))/2. So we have an equation which gives cos^2(x) in a nicer form which we can easily integrate using the reverse chain rule. Wanda, (1) The minus sign: The function is nonnegative everywhere, but the integral from b to a of a function is the negative of the integral from a to b.This follows from the definition; and it is, as Martha Stewart would say, a good thing, because it means the formulas for piecing integrals together will still work when one of them is backwards.
