tangent of f(x)=x^3-x

tangent of

f (x) = x^{3} - x

y = (3 a_{0}^{2} - 1) x - 2 a_{0}^{3}

Solution steps

Compute the tangent line to the general point

x = a_{0}

Find the tangent point:

(a_{0}, a_{0}^{3} - a_{0})

Find the slope of

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

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 = 3 a_{0}^{2} - 1

Find the line with slope m=

3 a_{0}^{2} - 1

and passing through

(a_{0}, a_{0}^{3} - a_{0}) : y = (3 a_{0}^{2} - 1) x - 2 a_{0}^{3}

y = (3 a_{0}^{2} - 1) x - 2 a_{0}^{3}
