Oh that's awesome. Thanks, I changed 1/2 to 1/4 and then renormalized the wave function, and everything works perfectly. Thanks a lot.

Well, sigma x comes out to 1/rad(2) for the sqrt((integral from -inf to +inf of Psi* x^2 Psi) - (integral from -inf to +inf of Psi* x Psi)^2). How would I change the wave function to make sigma x = 1 then?

Yeah, that's how I've been getting <x>. It must the be exp^(i x) that's causing the problems. The x in the exponent must be messing something up. How can I get around this?

I have tried this, the only problem is that the function must also have the momentum, -h bar, which requires another exponential term, exp(-i x). Also, sigma^2 would be 1, and that would have the form A * exp^(-i x)*exp^((-(x+1)^2)/2) where A = 1/ pi^(1/4) Because of the first exponential...

For some reason, I just can't find the function. I don't know how I could make a wave function that could possibly have a standard distribution of 1 and an expected value of -1, graphically.

Sigma x is the standard deviation of x.

Homework Statement Come up with a wave function Psi[x] that satisfies the given known values: <x>=-1 sigma x = 1 <p> = h bar Homework Equations The Attempt at a Solution So far I have this equation, which satisfies <x>, <p>, but not sigma x. 1/[Pi]^(1/4) E^(i (x + 2)) E^(-(1/2)...
