Well, show us your latest turn around the circle in working out this integral. You may have overlooked something simple.## Homework Statement

Some integration by parts problems require using it a few times :D

So when doing parts and one way doesn't work, what to do next?

However, it is easier to integrate e

Hint: you may not want to make u = z

Here is one of the lines from the last image you posted.

$$\frac{z^2e^{z^2}}{2} - \int \frac{2ze^{z^2}dz}{2}$$

The LaTeX script before it is rendered looks like this:

$ $\frac{z^2e^{z^2}}{2} - \int \frac{2ze^{z^2}dz}{2}$ $

Note that I put an extra space between each pair of $ symbols. That prevents the browser from rendering the script.

Fractions: \frac{}{}, with numerator in first pair of braces, and denominator in the second pair

Exponents: Use ^{} after the thing being raised to the power. If the exponent is a single character, the braces aren't needed.

Integrals (indefinite): \int

Integrals (definite): \int_a^b --Here a is the lower limit and b is the upper limit
