Rapid calculus - implicit differentiation equation of the tangent line

Uploaded by TheIntegralCALC on 07.11.2012

Find the equation of the tangent line of this function, at the given point.
Use implicit differentiation and apply product rule to take the derivative.
Remember to multiply by dy over dx every time you take the derivative of y.
Collect terms involving dy dx together on one side.
Factor out, and then solve, for dy dx.
Plug the given point into the derivative function to find the slope of the tangent line.
Plug the slope and the given point into formula for the equation of the tangent line.
Then simplify as much as possible.
