**[SOLVED] help with variatinal method**

Use a trial wavefunction of the form exp(-alpha*x^2/2) to compute an approximate ground state energy for the quartic oscillator with potential V(x) = c*x^4 using the variational method.

Here is what I have so far. We need to use the equation

E = integral((psi*)*Hamiltonian*psi)/integral((psi*)psi)

First we have to use the right hamiltonian. I have H = -h^2/2m(d^2)/(dx^2) + cx^4

No my question is, do I just have to take the integral of top and botton and thats it or am I missing something?

(sorry for the bad equation, but i suck at LaTeX)

thanks
