Finding antiderivative by Maclaurin series
I want to find p ( x ) d x where:
p ( x ) = e x 2 2 2 π ..
This function can not be manually computed so I am using Maclaurin series to find the antiderivative. I believe the Maclaurin series for this function would be:
1 2 π n = 0 x 2 2 n n ! .
The bounds of integration would be from -1 to 1. How would I create a Maclaurin series for the antiderivative from this?

Explanation:
We can integrate the Maclaurin Series term by term as follows.
2 0 1 1 2 π n = 0 ( x 2 2 ) n n !
2 π n = 0 0 1 ( 1 ) n x 2 n 2 n n !
2 π n = 0 ( 1 ) n x 2 n + 1 2 n n ! ( 2 n + 1 ) | 0 1
2 π n = 0 ( 1 ) n 2 n n ! ( 2 n + 1 ) 0.682689492
From this series, we get an approximation of the true value.
