## Homework Equations

## The Attempt at a Solution

[/B]

The above image is my initial attempt at the first equation.

I was told the way to find out if its normalized is to use:

##\int^{+\infty}_{-\infty} \Psi^2 dx## = 1

but I think I'm misunderstanding part of the math involved. There's an example on Chegg with the problem solved, but in their example the variables that didn't square become zero after integration. And then, the remaining numbers become ... 1. Somehow.
