Verify that the function u(x, y, z) = log x^2 + y^2 is a solution of the two dimensional laplace equation u_xx + u_yy = 0 everywhere, except of course at the origin where f is not defined. verify that the following functions solve the wave equation, u_tt = u_xx u(x, t) = cos(4x) cos(4t) u(x, t) = f(x - t) + f(x + 1), where f is any differentiable function of one variable.
