tangent of 7sqrt(x)

tangent of

7 x

y = \frac{7}{2 a _{0}} x + 7 a_{0} - \frac{7 a _{0}}{2}

Solution steps

Compute the tangent line to the general point

x = a_{0}

Find the tangent point:

(a_{0}, 7 a_{0})

Find the slope of

y = 7 x : \frac{d y}{d x} = \frac{7}{2 x}

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{7}{2 a _{0}}

Find the line with slope m=

\frac{7}{2 a _{0}}

and passing through

(a_{0}, 7 a_{0}) : y = \frac{7}{2 a _{0}} x + 7 a_{0} - \frac{7 a _{0}}{2}

y = \frac{7}{2 a _{0}} x + 7 a_{0} - \frac{7 a _{0}}{2}
