Misc Math / Wave Equation Solution over R

(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?
