tangent of f(x)= 1/(sqrt(5x))

tangent of

f (x) = \frac{1}{5 x}

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

Solution steps

Compute the tangent line to the general point

x = a_{0}

Find the tangent point:

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

Find the slope of

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

Find the line with slope m=

- \frac{1}{2 5 a _{0}^{\frac{3}{2}}}

and passing through

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

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