derivative y=4x^2-13x-9/(x^4)

Lösung

ableitung von

y = 4 x^{2} - 13 x - \frac{9}{x ^{4}}

8 x - 13 + \frac{36}{x ^{5}}

Schritte zur Lösung

\frac{d}{d x} (4 x^{2} - 13 x - \frac{9}{x ^{4}})

Wende die Summen-/Differenzregel an:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{d}{d x} (4 x^{2}) - \frac{d}{d x} (13 x) - \frac{d}{d x} (\frac{9}{x ^{4}})

\frac{d}{d x} (4 x^{2}) = 8 x

\frac{d}{d x} (13 x) = 13

\frac{d}{d x} (\frac{9}{x ^{4}}) = - \frac{36}{x ^{5}}

= 8 x - 13 - (- \frac{36}{x ^{5}})

Vereinfache

= 8 x - 13 + \frac{36}{x ^{5}}

t an g e n t f (x) = \frac{2}{x}, (- 3, - \frac{2}{3})

\frac{d}{d x} (x - ln (x^{2}))

\int - \frac{3}{x} d x

d er i v a t i v e f (x) = (x - 1) (x^{2} + 2)^{3}

\int sin (x) cos (x) d x
