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.

Graph the curves and determine the points of intersection.

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