I think you did the implicit differentiation wrong. Here's what I obtained: Substitute these values in the expression above: So now we have: Try solving for and see if you can get an answer.

Yup Yup :3 Then the answer is -1 && I see what I did wrong, too. I didn't take the derivative properly when I did product rule :33 Thank you very much ! =)
