Homework Statement
Find the expectation value of the Energy the Old Fashioned way from example 2.2.
Homework Equations
##\left< E \right> =\frac { 480\hbar ^{ 2 } }{ \pi ^{ 4 }ma^{ 2 } } \sum _{ odds }^{ \infty }{ \frac { 1 }{ { n }^{ 4 } } } ##
The Attempt at a Solution
Never mind the details of the physics problem. I am confident of those bits since it is from an example.
Using a symbolic math program, how to I only evaluate odds of a summation? I use sage and Wolfram Alpha normally. I tried using sin(pi*n/2)^2 to eliminate the even terms, but neither program seemed to take well to that.
Thanks,
Chris
