Often, students forget the product rule when using implicit.
Now, plug in your given points to find the slope.
Next, use your given points and the slope in y=mx+b to solve for b. You're done.
I need help with these two problems! I keep working them out and getting wrong answers! BAH!
1.) Use implicit differentiation to find the equation of the tangent line to the curve at the point . The equation of this tangent line can be written in the form where is:
and where is:
I keep got 0 for this one and its not right! :S
If and , find by implicit differentiation.
