tangent of x^3

tangent of

x^{3}

y = 3 a_{0}^{2} 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})

Find the slope of

y = x^{3} : \frac{d y}{d x} = 3 x^{2}

Compute the slope of

y = x^{3}

x = a_{0} : m = 3 a_{0}^{2}

Find the line with slope m=

3 a_{0}^{2}

and passing through

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

y = 3 a_{0}^{2} x - 2 a_{0}^{3}

- \frac{1}{x}

y = x^{3} - 2 x^{2} + 4, (2, 4)

e^{x^{2}}

3 x + y - 15 = 0

f (x) = 2 x^{2} + 7 x - 9, at x = - 3
