tangent of f(x)= x/(1+x^2),0.4,\at x=2

tangent of

f (x) = \frac{x}{1 + x ^{2}}, 0.4, at x = 2

y = - \frac{3}{25} x + \frac{16}{25}

Solution steps

Find the tangent point:

(2, \frac{2}{5})

Find the slope of

f (x) = \frac{x}{1 + x ^{2}} : \frac{df ( x )}{d x} = \frac{1 - x ^{2}}{( 1 + x ^{2} ) ^{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 = - \frac{3}{25}

Find the line with slope m=

- \frac{3}{25}

and passing through

(2, \frac{2}{5}) : y = - \frac{3}{25} x + \frac{16}{25}

y = - \frac{3}{25} x + \frac{16}{25}

x \to 0 lim (1^{\frac{1}{x}})

\frac{\partial}{\partial x} (x cos (y) + y e^{x})

e^{\frac{2}{3}}

\int_{- \frac{π}{4}}^{\frac{π}{4}} 1

\frac{d}{d x} (A (2 e^{- x} x - e^{- x} x^{2}))
