tangent of f(x)=(20x)/(x^2-5),(5,5)

tangent of

f (x) = \frac{20 x}{x ^{2} - 5}, (5, 5)

y = - \frac{3}{2} x + \frac{25}{2}

Solution steps

Find the slope of

f (x) = \frac{20 x}{x ^{2} - 5} : \frac{df ( x )}{d x} = \frac{20 ( - x ^{2} - 5 )}{( x ^{2} - 5 ) ^{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}{2}

Find the line with slope m=

- \frac{3}{2}

and passing through

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

y = - \frac{3}{2} x + \frac{25}{2}

x \to 0 lim (\frac{a x ^{2} + b x ^{3}}{c x ^{2} + d x ^{3}})

\frac{d}{d x} ((\frac{4}{5} x)^{4})

\int_{0}^{3} π (4 3 y)^{2} d y

5^{4 x}

\frac{d}{d x} ((7 x^{4} + 10)^{5})
