Title: How to find the equation of a tangent line at a point? Post by: tony on Feb 27, 2013 My textbook really sucks at giving enough examples of problems so I could not find an example like this:
y = (sqrt(x)) / (x+1) at the point (9 ,0.3) I figured I needed to differentiate the function using the quotient rule and I got: (((x+1) / (2sqrt(x)) - sqrt(x)) / (x+1)^2 But where do I go from there?
