Let y be defined implicitly by the equation ln(8y)=5xy.
A) Use implicit differentiation to find the second derivative of y with respect to x. ((d^2)y)/(d(x^2)= ?
Note: Your answer should only involve the variables x and y.
You should simplify your answer as much as possible.
B) Find the point on the curve where ((d^2)y)/(d(x^2)=0.
