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

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.
