Assume ψ(x,0)=e^(-λ*absvalue(x)) for x ± infinity, find Φ(k)
Φ(k)=1/√(2π)* ∫e(-λ*absvalue(x))e(-i*k*x)dx,-inf, inf[/B]
The Attempt at a Solution, my thought was Convert the absolute value to ± x depending on what of the number line was being integrated.[/B]
Now fixing abs value
the integrand for one half of the number line looks like:
For which i get: after limits are taken for that half of the integral
Then similar integral for other half
Is this the right track or am i totally off?
