It's just disappointing. Worked through assignments all term with equations and everything widely available, now come exam it's an added layer of difficulty on top of everything.

Just out of curiosity, I'm interested with how other undergrad courses do with these. I'm about to sit a QM exam. In our exam, we are given a list of constants and integral identities. No equations at all ... and that's an awful lot of equations for the 30ish hours of lectures we have had...

Homework Statement Given a square well, Infinite wall at x=0 Wall height U for x>L For E<U, find solutions to the schrondinger equation inside the well, and beyond x>L which satisy boundary conditions for x=0 and x=\infty Taking conditions at x=L, find the allowable energies of the...

Hi there I'm doing a double degree in physics and mech engineering. Up until now, I've been using my good old Ti-83 and has served me well but me thinks it may be time to maybe invest in a good calculator for the future. I would prefer to stay with the TI brand since I'm very...

You have: x'(t)=6-8t+t^{2} delta x can be calculated with simple substitution. You need to find an equation for both velocity and acceleration by means of differentiation. Recall the definitions for the terms: average, velocity and speed (a plot might help). Direction changes when...

Hi. What you want to do is set the origin at variable positions. For a system to be in equilibrium you need the sum of torques to be zero. If you set an origin centered at the line of action, you will effectively eliminate any torque the force produces. That leaves you with 3 torques to...

Ahh thanks. I can do the Lorentz. It does seem like a much simpler method. Appreciate it mate :)

I'm just trying to figure out the basic concepts of relativity and I just seem to confuse myself more the more I think about it. Homework Statement Consider a moving observer O' at velocity v in one dimension. Two simultaneous events, each distance L away from the observer occur. What is the...
