Question

Use implicit differentiation to find the slope of the tangent line to the curve
3x2−3xy+2y3=−60
at the point (−2,−3).
m=?

Answer 1

I got -0.0625 and it's suppost to be 0.05
what did i do wrong?

Answer 2

Hmm yah I'm coming up with 0.05, maybe getting a little mixed up in the middle somewhere? Did you get 2 y' terms when you differentiated?
I kinda wizzed through the simplification, sorry about that.
