In Problems 40-44, find the linear, L(x, y), and quadratic, Q(x, y), Taylor polynomials valid near (1, 0). Compare the values of the approximations L(0.9, 0.2) and Q(0.9,0.2) with the exact value of the function f(0.9, 0.2).\fIn Problems 45-46, show that the function satisfies Laplace's equation, F + F = 0. 45. F(x, y) = e-* sin y
