One of the practice problems in my Calculus book is as follows: The graph of y=$8/(x^2-4)$ is called the Witch of Agnesi.
(a) Find y'
d/dx (u/v) = (v du/dx - u dv/dx)/($v^2$)
Assuming I've gotten (a) correct, I then am asked (b) Find the equation of the tangent (in slope-intercept form) at the point (2,1).
Can anyone help me get rolling on this one?
