tangent of 1/x ,\at x=2

tangent of

\frac{1}{x}, at x = 2

y = - \frac{1}{4} x + 1

Solution steps

Find the tangent point:

(2, \frac{1}{2})

Find the slope of

y = \frac{1}{x} : \frac{d y}{d x} = - \frac{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{1}{4}

Find the line with slope m=

- \frac{1}{4}

and passing through

(2, \frac{1}{2}) : y = - \frac{1}{4} x + 1

y = - \frac{1}{4} x + 1
