Question 5: 3.) Find the general solution of the partial differential equation: ("W/am = 311/6: b) _ When solving the heat equation using the separation of variables method, reach a. point where T'(t)/T(t) = X\"($)/X(z) = C and we used a. negative constant (i.e., C = A2). Show that if we used a. positive constant instead for C, for a. rod of length [3 and assuming boundary conditions u(0, t) = 0 = 110?, t) that the only solution to the partial differential equation is u(m, t) = 0 for all .1: and all t
