I thought Wave Equation was a second derivative in time and spatial terms, instead of first derivative...

[chinnywurl]

@tunoheavy d^2 u/d t^2 - c^2d^2 u/d x^2 = (d/dt -cd/dx)(d/dt + c d/dx)u so either component is thought of a wave travelling in opposite directions. So as he terms it .. each bracket is a single wave equation.

seriously this is really simple

[circusboy90210]

here's an idea. how about the same problems in a base 12 arguement?

its not all to bad, i like this, thanks for uploading, it helps understand concepts, this guy teaches in a strange way, his examples are very simplistic, which although applicable to many DE's, he skims through some sections, or describes them not vaguely, but i guess...its just that he refrences his past work a lot? but its decent.. i enjoyed

[brightscience]

why does this have to be so hard?
