Find the slope-intercept equation for the tangent line to the curve: y=ln((1+x)/(1-x)) at x=0.1

Answer 1

y-1=2x

Answer 2

how did you do that?

Answer 3

c 2 points are given and the last thing u need is m (slope) which in this case will be dy/dx which is = 2 in this case then eq of line is
y-y1=m(x-x1)
y-1=2(x-0)
y-1=2x
if u understood plz do tell..
