Hi, everyone. I'm struggling with an integral evaluation - any help would be appreciated!
For starters, I'm trying to find the uncertainty in position of a particle in a carbon nanotube described by a specific wave function. More importantly, I've come across an integral evaluation which I just am not sure is correct. Here is the full calculation (which I've also attached):
My main question: if n is a positive integer, can the cos(2ax) term really be zero (which seems to be what the final product implies)? I can't find any situation where that term is zero (if n is a positive integer), or any situation in which I get the final product. Does anyone have any insight?
Thanks for the help!
