Homework Statement
Find the tangent equations to the curve y^2= x-1/x+1 at the points with x=2
Homework Equations
y=mx+b
dy/dx
The Attempt at a Solution
I tried to solve in order to y: y=sqrt((x-1)/(x+1))
Then I derived to obtain the slope, but this is the part that I don't know if it is correct. Do I need to derive the equation to get the slope, and after getting the slope I substitute the x in the equation that I got to get the tangent equation? I'm stuck here
Thanks in advance
