Separation of Variables Heat flows along an infinite (in the y-direction) strip of width a (in the x-direction). Find the general solution u(x, y, t) to the two-dimensional heat equation ди - k√² u = 0 Ət subject to the boundary conditions: u(0, y, t) = 0 = u(a, y, t); — u(x, y, t) lim u(x, y, t) = 0. x+h = = 0; and |t=0
