    witch of agnesi? (simple)

    Another problem that I need help with...

    Find the tangent to the "witch of Agnesi", y=8/4+x^2 at the point (2,1).

    I think I have an idea of what to do, but I want to make sure..

    Thanks

    1. Differentiate y wrt x. (Use chain rule)

    2. Plug in the x-coordinate of P(2,1) to determine the slope of the tangent.

    3. Use the point-slope-formula of a straight line to get the equation of the tangent.
