tangent of 9x^2-x^3

tangent of

9 x^{2} - x^{3}

y = (18 a_{0} - 3 a_{0}^{2}) x + 2 a_{0}^{3} - 9 a_{0}^{2}

Solution steps

Compute the tangent line to the general point

x = a_{0}

Find the tangent point:

(a_{0}, 9 a_{0}^{2} - a_{0}^{3})

Find the slope of

y = 9 x^{2} - x^{3} : \frac{d y}{d x} = 18 x - 3 x^{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 = 18 a_{0} - 3 a_{0}^{2}

Find the line with slope m=

18 a_{0} - 3 a_{0}^{2}

and passing through

(a_{0}, 9 a_{0}^{2} - a_{0}^{3}) : y = (18 a_{0} - 3 a_{0}^{2}) x + 2 a_{0}^{3} - 9 a_{0}^{2}

y = (18 a_{0} - 3 a_{0}^{2}) x + 2 a_{0}^{3} - 9 a_{0}^{2}

5 + 2 t cos (2 t)

\frac{d}{d x} (2 (π - e)^{4})

y = e^{- 9 t}

n = 3 \sum \infty 2^{- n + 2}

\int \frac{cot ^{2} ( 11 x )}{sec ( 11 x )} d x
