Thank you very much http://img104.herosh.com/2010/11/18/211847127.jpg" But the show of the integral of Sec[\[Theta]] does not converge on {0,2 \[Pi]} Is this true!

Find < px >,< p > and < p2 > for the 1s electron ofa hydrogen atom. i am tried the solution but momentum operators Differential for x or y or z and the wave equation depends on the r !

Thank you Your participation in the subject to others if allowed

The problem lies in the y'(0) = 0 As a result, all the constants equal to zero

Thank you very much But I have a problem is all Constants equal to zero! What reason?

I can not! please
