# Problem with normalisation, or should i say integration

1. The problem statement, all variables and given/known data

Consider the wave packet $\psi(x)\equiv ψ(x, t = 0) = Ce^{i\omega x}e^{-\left|x\right|/2\Delta x}$ where C is a normalisation constant.

Normalise $\psi(x)$ to unity.

2. Relevant equations

3. The attempt at a solution

I know the normalisation condition. My problem is when I have ...

$\left|C\right|^{2}\int e^{-\left|x\right|/\Delta x} dx = 1$

Any help will be MUCH appreciated.

Say delta x=x-x0

Good thinking! But this makes the problem even harder . lolzz. because I have literally NO idea how to integrate such an expression!

Thank U! I just got lost like U did, but my professor gave this idea.
