tangent of ((2x-1)/(x+1)),2

tangent of

(\frac{2 x - 1}{x + 1}), 2

y = \frac{3}{( a _{0} + 1 ) ^{2}} x + \frac{2 a _{0}^{2} - 2 a _{0} - 1}{( a _{0} + 1 ) ^{2}}

Solution steps

Compute the tangent line to the general point

x = a_{0}

Find the tangent point:

(a_{0}, \frac{2 a _{0} - 1}{a _{0} + 1})

Find the slope of

y = \frac{2 x - 1}{x + 1} : \frac{d y}{d x} = \frac{3}{( x + 1 ) ^{2}}

EN : T i tl e G e n er a l Eq u a t i o n Sl o p e A t P o in t 2 Eq : m = \frac{3}{( a _{0} + 1 ) ^{2}}

Find the line with slope m=

\frac{3}{( a _{0} + 1 ) ^{2}}

and passing through

(a_{0}, \frac{2 a _{0} - 1}{a _{0} + 1}) : y = \frac{3}{( a _{0} + 1 ) ^{2}} x + \frac{2 a _{0}^{2} - 2 a _{0} - 1}{( a _{0} + 1 ) ^{2}}

y = \frac{3}{( a _{0} + 1 ) ^{2}} x + \frac{2 a _{0}^{2} - 2 a _{0} - 1}{( a _{0} + 1 ) ^{2}}
