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{d}{d x} (ln (x) e^{x})

\frac{d}{d x} ((5 x - 4)^{2})

f (x) = ln (\frac{1}{x})

\frac{d y}{d t} = y - 2 t

\int \frac{x}{x + 8} d x
