tangent of x^2-1

tangent of

x^{2} - 1

y = 2 a_{0} x - a_{0}^{2} - 1

Solution steps

Compute the tangent line to the general point

x = a_{0}

Find the tangent point:

(a_{0}, a_{0}^{2} - 1)

Find the slope of

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

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 = 2 a_{0}

Find the line with slope m=

2 a_{0}

and passing through

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

y = 2 a_{0} x - a_{0}^{2} - 1

\int_{0}^{1} (x^{2} + 1) (e^{- x}) d x

in v erse l a pl a ce \frac{1}{s ^{2} + 4 s + 8}

d er i v a t i v e g (x) = \frac{3}{6 x + 8}

\int x^{2} - 2 x - 3 d x

(1 - 2 y + x) \frac{d y}{d x} + y = 2 x - 1
