tangent of x-x^3(1)

tangent of

x - x^{3} (1)

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

Find the slope of

y = x - x^{3} 1 : \frac{d y}{d x} = 1 - 3 x^{2}

Compute the slope of

y = x - x^{3} 1

x = a_{0} : m = 1 - 3 a_{0}^{2}

Find the line with slope m=

1 - 3 a_{0}^{2}

and passing through

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

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

\int 7 arctan (x) d x

f (x) = \frac{1}{x} + 200

\frac{d}{d t} (\frac{t ^{2}}{10})

f (x) = \frac{1}{x ^{3}}, at x = 5
