Find the solution to the differential equation Vf(r, 6, 4) = 0 Throughout R, with the following condition to the border: f(r a, 0, 4) = Vo For 0 e [0,7/4), f(r a, 0, ) = -Vo %3D O (T/4, 7/2], f(r = a, 0, 4) = Vo For For (T/2, 3T/4], f(r = a, e, 6) = Vo tor e (3T/4, 7]. Where V, is a real number. Explain your result when Vo = 0
