Let y be defined implicitly by the equation In(3y) = 5xy. Use implicit differentiation to find the first derivative of y with respect to . dy 512 da 1 - 5xy Use implicit differentiation to find the second derivative of y with respect to a. da2 Note: Your answer should only involve the variables a and y. You should simplify your answer as much as possible before entering it into WeBWork. Find the point on the curve where - O. da 2 day da 2 = 0 at the point (x, y) =
