What is the menaing of "standing plane waves"? Hi All, For me, English is my second language and I am not good is waves also. Here is a passage from QM: "For all practical boundary conditions, the waves must be standing plane waves of all possible wavelengths and amplitudes" What is...

Hi all, I have an expression like this. ln(1+exp(x)) and x is a huge number. Can I write like this ? ln(1+exp(x)) = x. If it is right, how can I prove this?

Thanks Data. I am able to get the answer after following your suggestions.

Hi All, While going through quantum conductnace derivation, I got stuck by an integral. I = ((e*(h/2pi))/(m*pi)) Integral from 0 to infinity dt / ( exp (((((h/2pi)^2 * t)/(2*m)) - Ef) / kT)) + 1) The answer is I =...
