In each problem, solve the initial-boundary value prob- lem of this section for the rectangle 0 < x 2. k=4, L=2, K = 3, f(x, y) = x(2-x) sin(y) (3 - y) 3. k=1,L=K=,f(x, y) = sin(x)y cos(y/2) In each problem, solve the initial-boundary value prob- lem of this section for the rectangle 0 < x 2. k=4, L=2, K = 3, f(x, y) = x(2-x) sin(y) (3 - y) 3. k=1,L=K=,f(x, y) = sin(x)y cos(y/2)
