tangent of y=x^3-2x+2

tangent of

y = x^{3} - 2 x + 2

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

Solution steps

Compute the tangent line to the general point

x = a_{0}

Find the tangent point:

(a_{0}, a_{0}^{3} - 2 a_{0} + 2)

Find the slope of

y = x^{3} - 2 x + 2 : \frac{d y}{d x} = 3 x^{2} - 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 = 3 a_{0}^{2} - 2

Find the line with slope m=

3 a_{0}^{2} - 2

and passing through

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

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

What is the tangent of y=x^3-2x+2 ?
The tangent of y=x^3-2x+2 is y=(3a_{0}^2-2)x-2a_{0}^3+2
