sqrt(2/a) cos(npix/a) if it is this then
psi^2= (2/a)*cos^2 (3pix/a)
for this to equal zero x=a/6 or -a/6
so is that the correct answer for part 2?
Does anyone have any bright ideas for part 3?
thanks for the help by the way
Really? I can't see why, looking at this diagram surely it describes a sine function at n=3?

They all appear to be sine functions, because at the walls there are nodes. Maybe I am looking at it wrong actually, I can see how the symmetry of the n=3...
Hi, (first ever post)
I have the following three problems
1) A particle is in the ground state of an infinite well from 0<x<a. Find the probability that it is in the middle half of the well.
I think I have managed this, its just the integral of the wave function squared then I put in the...
