What is implied by the word "weird", is it just something unexpected that comes up or something that hasn't been discussed in the course? Thanks!

##### Misc Math / Lecture Notes 7 - Code problem
« on: October 13, 2012, 05:56:12 PM »
In Lecture Notes 7 - 1D Wave Equation: IBVP, there was code below equation (10) and (15) that didn't get turned into text. It was $Oct$ and (\ref{eq-4}), what do these stand for? Thank you!

Homework 4 was taken down off the website. Is it still due next week or was it only meant as a set of review questions.
Thanks!

##### APM346 Misc / HW Solutions Posting on Forum
« on: October 02, 2012, 02:08:48 PM »
I was just wondering what the policy was about posting solutions to problem sets on the forum. On the general announcement, it indicates that posting solutions is to be done no earlier than 1 day after the deadline (Tuesday night), yet all the solutions are already posted.

##### Misc Math / Wave Equation Solution over R
« on: September 26, 2012, 02:02:55 PM »
(With all appropriate boundary conditions defined) When the wave equation is defined for x>0, we can find a solution to the wave equation for x < ct and 0 < x < ct. If the equation is defined for all x, how do the solutions change?

##### Misc Math / Heat Wave Equation Solution Integral
« on: September 25, 2012, 08:04:29 PM »
After we determined the solution to the heat wave equation, we took the integral from negative infinity to some x. The solution was in the form of a Normal Distribution function where in statistics the integral indicates the probability that we randomly choose a value within that interval. I was wondering what are the physical implications of this same integral in the wave equation? Does the area under the solution indicate the energy in the system up to that point or does it have some other meaning?

For Part (c) of Problem 4, does it refer to the solution of (5) or (6) or both?
