Solving for constant in an integral
I'm in a bit of a pickle,revising for an exam, but there's one stumbling block i'm getting at, evaluating this so that I have a finite value for a. I've obtained the anti-derivative, I'm i'm facing hell trying to complete the problem. Any pointers will be appreciated. The limits are from negative infinity to positive infinity

This has to be treated as an improper integral. However, it's impossible for the given integral to equal 1. Is this the original question?

If that's the correct question then it has an error in it. See your teacher.
