This is easy to see why this is true in general. Let’s suppose that we want to find the area of the region shown below. From Calculus I we know that this area can be found by the integral, A = ∫b ag2(x) − g1(x)dx. Mr. Jones. The definite integral gives you a SIGNED area, meaning that areas above the x-axis are positive and areas below the x-axis are negative. That is why if you integrate y=sin (x) from 0 to 2Pi, the answer is 0. The area from 0 to Pi is positive and the area from Pi to 2Pi is negative -- they cancel each other out.
