tangent of f(x)=x-1/x+ln(x),\at x=1

tangent of

f (x) = x - \frac{1}{x} + ln (x), at x = 1

y = 3 x - 3

Solution steps

Find the tangent point:

(1, 0)

Find the slope of

f (x) = x - \frac{1}{x} + ln (x) : \frac{df ( x )}{d x} = 1 + \frac{1}{x ^{2}} + \frac{1}{x}

Find the line with slope m=

3

and passing through

(1, 0) : y = 3 x - 3

y = 3 x - 3
