Hi everyone, So my quantum physics teacher gave this problem to solve as homework: An experiment to watch neutron diffraction was made. The neutron wavelength measured was 18.45 Angstroms. The double slit was created by putting a thread in the middle of a single slit. The dimensions of the...

Thanks everyone! I feel really stupid right now, my mistake was quite dumb... I had forgotten that when you use quadratic formula, if the quadratic coefficient (a) is not 1, you'll have a*(x-z1)(x-z2). I often forget the most basic stuff. Thank you!

Hi! I'm new here, been a fan of this site for years, but only now I felt the need of registering. Homework Statement Use the Residue Theorem to solve the integral: ∫[(cos(2t)) / (5-4*cos(t)) ] dt from t=0 to t=2pi2. The attempt at a solution I did a variable change z=eit. With that...
