tangent of ((3x+5))/(1+x)

tangent of

\frac{( 3 x + 5 )}{1 + x}

y = - \frac{2}{( 1 + a _{0} ) ^{2}} x + \frac{3 a _{0}^{2} + 10 a _{0} + 5}{( a _{0} + 1 ) ^{2}}

Solution steps

Compute the tangent line to the general point

x = a_{0}

Find the tangent point:

(a_{0}, \frac{3 a _{0} + 5}{1 + a _{0}})

Find the slope of

y = \frac{3 x + 5}{1 + x} : \frac{d y}{d x} = - \frac{2}{( 1 + x ) ^{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{2}{( 1 + a _{0} ) ^{2}}

Find the line with slope m=

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

and passing through

(a_{0}, \frac{3 a _{0} + 5}{1 + a _{0}}) : y = - \frac{2}{( 1 + a _{0} ) ^{2}} x + \frac{3 a _{0}^{2} + 10 a _{0} + 5}{( a _{0} + 1 ) ^{2}}

y = - \frac{2}{( 1 + a _{0} ) ^{2}} x + \frac{3 a _{0}^{2} + 10 a _{0} + 5}{( a _{0} + 1 ) ^{2}}
