The full step-by-step solution to problem: 7.3.4 from chapter: 7.3 was answered by , our top Math solution expert on 01/25/18, 04:21PM. The answer to “Solve u t = k1 2u x2 + k2 2u y2 on a rectangle (0 < x < L, 0 <y subject to the initial conditions u(x, y, 0) = 0 and u t (x, y, 0) = (x, y). [Hint: You many assume without derivation that the product solutions u(x, y, t) = (x, y)h(t) satisfy d2h dt2 = c2h and the two-dimensional eigenvalue problem 2+ = 0, and you may use results of the two-dimensional eigenvalue problem.] Solve the initial value problem if (a) u(0, y, t) = 0, u(L, y, t) = 0, u y (x, 0, t) = 0, u y (x, H, t)=0 * (b) u x(0, y, t) = 0, u x(L, y, t) = 0, u y (x, 0, t) = 0, u y (x, H, t)=0 (c) u(0, y, t) = 0, u(L, y, t) = 0, u(x, 0, t) = 0, u(x, H, t)=0.” is broken down into a number of easy to follow steps, and 153 words.
