1. ## Integrate

\int{e^{x^2}}\,dx

I really don't know where to go with this

mchalurin series?

maclaurin series ... yes.

3. so would it be

$\begin{array}{l}
{e^x} = \sum\limits_{n = 0}^\infty {\frac{{{x^n}}}{{n!}}} \\
{e^{{x^2}}} = \sum\limits_{n = 0}^\infty {\frac{{{{({x^2})}^n}}}{{n!}}} \\
\end{array}

$

Yes.

5. How would I intergrate both sides though o.o

Where has this question come from?

I assumed from your first post that you realise that $e^{x^2}$ has no elementary primitive. After expressing $e^{x^2}$ as a series, you integrate the series term-by-term.

7. calculus final exam

isn't there an easier way to do it than term by term what would the nth term in the series be?

Write the first few terms out, spot the pattern.
