<math>\frac{d^2g}{dt^2} - \frac{c^2d^2g}{dx^2} = \delta(\Delta x)\delta(\Delta t)</math>

<math>\frac{d^2g}{dt^2} - \frac{c^2d^2g}{dx^2} = \delta(\Delta x)\delta(\Delta t)</math>

This is not an easy equation to solve without  

This is not an easy equation to solve without using a Fourier transform. Therefore, we'll do just that, with G as the transformed function.

<math>G = \frac{1}{4\pi^2}\int{g(\Delta x,\Delta t)e^{-ik\Delta x}e^(i\omega\Delta t}d^3x dt}</math>

 

 

G = (copy from notes)

g = (copy)

g = (copy)
