tangent of f(x)= 1/(sqrt(5x)),\at x=9

tangent of

f (x) = \frac{1}{5 x}, at x = 9

y = - \frac{1}{54 5} x + \frac{1}{2 5}

Solution steps

Find the tangent point:

(9, \frac{1}{3 5})

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}{54 5}

Find the line with slope m=

- \frac{1}{54 5}

and passing through

(9, \frac{1}{3 5}) : y = - \frac{1}{54 5} x + \frac{1}{2 5}

y = - \frac{1}{54 5} x + \frac{1}{2 5}

\frac{36}{9 + x ^{2}}, 1

\frac{d}{d x} (3 x - 2 y)

\int_{1}^{e} \frac{ln ( 2 x )}{x} d x

\frac{d}{d t} (cos^{3} (3 t^{2}))

\frac{v}{v - 1}
