tangent of f(x)= 2/x ,\at x=-1

tangent of

f (x) = \frac{2}{x}, at x = - 1

y = - 2 x - 4

Solution steps

Find the tangent point:

(- 1, - 2)

Find the slope of

f (x) = \frac{2}{x} : \frac{df ( x )}{d x} = - \frac{2}{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 = - 2

Find the line with slope m=

- 2

and passing through

(- 1, - 2) : y = - 2 x - 4

y = - 2 x - 4

\frac{1}{x} d y - \frac{y}{x ^{2}} d x = 0

n = 1 \sum \infty (\frac{2}{7})^{n}

y^{^{'}} = \frac{- 2 x}{y}

\frac{d}{d x} (- 2 x^{5} + \frac{1}{2 x ^{2}})

y^{^{''}} + 25 y = - 50 sin (5 t)
