tangent of f(x)=(-6x)/(x^2+1),(0,0)

tangent of

f (x) = \frac{- 6 x}{x ^{2} + 1}, (0, 0)

y = - 6 x

Solution steps

Find the slope of

f (x) = \frac{- 6 x}{x ^{2} + 1} : \frac{df ( x )}{d x} = - \frac{6 ( - x ^{2} + 1 )}{( x ^{2} + 1 ) ^{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 = - 6

Find the line with slope m=

- 6

and passing through

(0, 0) : y = - 6 x

y = - 6 x

x^{2} + 4

\int \frac{1}{sin ( \frac{y}{2} )} d y

\int_{0}^{t} \frac{1}{1 + r} d r

\int - 4 x - 8 d x

n = 1 \sum \infty 5 e^{- 6 n}
