How To Solve Pde Using Fourier Transform. Our goal now is to solve the pde in equation [1] subject to the condition in equation [2]. An exercise asks me to solve it for using fourier and laplace transform:

Using the definition, the fourier transform of this is (fg)^= z 1 1 z 1 1 f(x y)g(y)e ikxdydx using the change of variables z= x y, this becomes z 1 1 z 1 1 f(z)g(y)e ik(y+z)dydz= z 1 1 f(z)e ikzdz z 1 1 g(y)e ikydy = f^(k)^g(k); Using the fourier transformto solve pdes in these notes we are going to solve the wave and telegraph equations on the full real line by fourier transforming in the spatial variable. Which is just the last formula in.
