CPM Homework Help : CALC Problem 9-112

Find the area of the region bounded by the curves $f(x) = x + 1$ , $g(x) = x^2 − 1$ , and $h(x) =\operatorname{cos}^{−1} x$ which includes the origin.

Step 1:

Graph the curves and determine the points of intersection.

For the second integral, use integration by parts.
Let $f =\operatorname{ cos}^{–1}(x)$ and $dg = 1dx$ .
