Question 1. Solve the following IVPS for the 2D wave on the rectangle [0, 1] x [0, 1] (where we assume that the solution u is always zero on the boundary): 1. Utt :Au u(x, y,0) = – 10 sin(37x) sin(7y) Uz (x, y, 0) = sin(7x) sin(Ty) 2. (for this one, you can use a computer algebra software to compute the integrals) Utt = Δυ u(r, y, 0) = x(x – 1)°y(y – 1)³ u(r, y, 0) = sin(rr) sin(ry)
