Please show work, thank you so much!!

Suppose f is a differentiable function of a and y and g(u, v) = f(uv + v, sin(4u + 3v + 1)). (Hint: Let = = uv + v and y = sin(4u + 30 + 1).) a. On your paper, draw a tree diagram to calculate gu. (Leave the answerbox blank) b. Using your tree diagram, write the formula for gu on your paper (Leave the answerbox blank) C. f g fu (0,0) -3 4 -5 (-1,1) 1 -3 - 8 3 Use the table of values above to calculate gu ( - 1, 1). Be very careful when you evaluate. Keep all your variables straight. gu ( - 1, 1) =
