Lösung

ableitung von

f (x) = x^{2} + 5 - 3 x^{- 2}

2 x + \frac{6}{x ^{3}}

Schritte zur Lösung

\frac{d}{d x} (x^{2} + 5 - 3 x^{- 2})

Wende die Summen-/Differenzregel an:

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

= \frac{d}{d x} (x^{2}) + \frac{d}{d x} (5) - \frac{d}{d x} (3 x^{- 2})

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

\frac{d}{d x} (5) = 0

\frac{d}{d x} (3 x^{- 2}) = - \frac{6}{x ^{3}}

= 2 x + 0 - (- \frac{6}{x ^{3}})

Vereinfache

= 2 x + \frac{6}{x ^{3}}

x \to \infty lim ((\frac{13 x}{13 x + 3})^{5 x})

\int \frac{2 x - 4}{( x ^{2} - 4 x + 7 ) ^{2}} d x
