12-111.

The function has derivatives of all orders within its radius of convergence of

**about**

*and its Maclaurin series is*

**.**

Write the first four derivatives of

.Remember, 3

is just a number, so:^{n}Expand the Maclaurin series of

out to four terms. Then find the integral of this polynomial,.
