I will drop your lowest exam grade. Second hourly exam is next Monday. Recall, the hourlies make up 40% of the grade. Course requirements
tips and tricks
- I don't expect exactitude in numerical calculations. So as far as I'm
concerned 1.9 = 3 and π = 3 so 1.9π = 6
- lots of people messed up exponents when doing division. 109 / 10 − 9 = 1018
- break up complicated numerical factors involving multiplications and divisions into small pieces. First do the numerator, then do the denominator and then get your final estimate.
- lots of people messed up: | eIkx | 2. This is 1!
- some people used and some used .
I didn't take off for this. But it does change the sign of the momentum.
- A Gaussian is centered at x0. You can
show this by integration, but it should be sufficiently well known that you merely state it as a fact.
