10010 \frac{1}{10} (10 + t^{2}) - \frac{20}{3} (t^{2} + 10)^{\frac{3}{2}} + \frac{1}{5} (10 + t^{2})^{\frac{5}{2}} + C

Schritte zur Lösung

\int \frac{t ^{5}}{t ^{2} + 10} d t

Trigonometrische Substitution anwenden

= \int 10010 tan^{5} (u) sec (u) d u

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 10010 \cdot \int tan^{5} (u) sec (u) d u

Umschreiben mit Hilfe von Trigonometrie-Identitäten

= 10010 \cdot \int (- 1 + sec^{2} (u))^{2} tan (u) sec (u) d u

Wende U-Substitution an

= 10010 \cdot \int (- 1 + v^{2})^{2} d v

Multipliziere aus

(- 1 + v^{2})^{2} : 1 - 2 v^{2} + v^{4}

= 10010 \cdot \int 1 - 2 v^{2} + v^{4} d v

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= 10010 (\int 1 d v - \int 2 v^{2} d v + \int v^{4} d v)

\int 1 d v = v

\int 2 v^{2} d v = \frac{2 v ^{3}}{3}

\int v^{4} d v = \frac{v ^{5}}{5}

= 10010 (v - \frac{2 v ^{3}}{3} + \frac{v ^{5}}{5})

= 10010 sec (arctan (\frac{1}{10} t)) - \frac{2 sec ^{3} ( arctan ( \frac{1}{10} t ) )}{3} + \frac{sec ^{5} ( arctan ( \frac{1}{10} t ) )}{5}

Vereinfache

10010 sec (arctan (\frac{1}{10} t)) - \frac{2 sec ^{3} ( arctan ( \frac{1}{10} t ) )}{3} + \frac{sec ^{5} ( arctan ( \frac{1}{10} t ) )}{5} : 10010 \frac{1}{10} (10 + t^{2}) - \frac{20}{3} (t^{2} + 10)^{\frac{3}{2}} + \frac{1}{5} (10 + t^{2})^{\frac{5}{2}}

= 10010 \frac{1}{10} (10 + t^{2}) - \frac{20}{3} (t^{2} + 10)^{\frac{3}{2}} + \frac{1}{5} (10 + t^{2})^{\frac{5}{2}}

Füge eine Konstante zur Lösung hinzu
