Example 6: Area Under Cosine Curve
Find the area under one arch of the curve y = cos x. Figure 7.2.7 From Figure 7.2.7 we see that one arch lies between the limits x =  π/2 and x = π/2, therefore the area is = 1  (1) = 2. Trigonometric identities can often be used to get an integral into a form which is easy to evaluate.
