tangent of x^2-1/x

tangent of

x^{2} - \frac{1}{x}

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

Solution steps

Compute the tangent line to the general point

x = a_{0}

Find the tangent point:

(a_{0}, a_{0}^{2} - \frac{1}{a _{0}})

Find the slope of

y = x^{2} - \frac{1}{x} : \frac{d y}{d x} = 2 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 = 2 a_{0} + \frac{1}{a _{0}^{2}}

Find the line with slope m=

2 a_{0} + \frac{1}{a _{0}^{2}}

and passing through

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

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