Your work can be viewed below, but no changes can be made. 1. [SCalcCC2 3.6.02.] 2/2 points You are given the following equation. 4 x 2 + 9 y 2 = 36 (a) Find y ' by implicit differentiation. y ' = -(8x)/(18y) (-4x)/(9y) (b) Solve the equation explicitly for y and differentiate to get y ' in terms of x . (Note: The answer expected below is the most natural answer that you will get if you follow the procedure you learned in class and in the textbook. If you feel that your answer is correct and it is marked as incorrect, please multiply your answer by -1 and submit again. If this does not correct the problem then the difficulty is in your calculations and not in WebAssign's interpretation of your answer.) y ' = (1/2)(-(4/9)x^2+4)^(-1/2)(-(8/9)x) (-2x)/(3sqrt(9-x^2))
