Need help with part d). Thank you :)

Consider the function f : R2 → R given by f(x, y) = x²y + sin(xy) + 1 (a) Compute the partial derivatives at the point (1,0): fx(x, y) = fy(x, y) = fxx(x, y) = fxy(x, y) = fyx (x, y) = f yy(x, y) = (b) (1, 0) is of the function f. (c) The tangent plane to the graph of z = f(x, y) at the point (1, 0, 1) can be described by the equation x+ y+ z = se dt (d) If x = (s² + t²) and y = s – t², then at the point (s, t) = (1, 1), is equal to (e) The maximum rate of change of f(x, y) at the point (x, y) = (1, 0) is
