# Mathematical and Computational Methods in Physics and Engineering (fall 2016)

## Daily outline for Mon, Dec 5, 2016 9:10 AM (7 months ago)

### Review

assigned today:

Due today:
• standard-2D wave equation:

I can calculate and shape and frequencies of a circular drum head.

1. 12.10.13 through 12.10.15 (all of them)
2. Calculate the relative amounts of the first 10 frequencies for a circular drum with radius 1 excited by the function $$f(r)=e^{-r^2/0.2^2}$$
3. Calculate 5 different frequencies for a circular drum, at least one of which has an eigenfunction that is a function of $$\theta$$

# in class

• Talked about the final and due dates (everything due noon 12/20)
• build up an analogy between:
• Talked about $$J_0(r)$$ versus $$J_0(kr)$$
