Lösung

\int sec^{6} (x) tan^{6} (x) d x

Schritte zur Lösung

\int sec^{6} (x) tan^{6} (x) d x

Umschreiben mit Hilfe von Trigonometrie-Identitäten

= \int sec^{2} (x) (1 + tan^{2} (x))^{2} tan^{6} (x) d x

Wende U-Substitution an

= \int u^{6} (1 + u^{2})^{2} d u

Multipliziere aus

u^{6} (1 + u^{2})^{2} : u^{6} + 2 u^{8} + u^{10}

= \int u^{6} + 2 u^{8} + u^{10} d u

Wende die Summenregel an:

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

= \int u^{6} d u + \int 2 u^{8} d u + \int u^{10} d u

\int u^{6} d u = \frac{u ^{7}}{7}

\int 2 u^{8} d u = \frac{2 u ^{9}}{9}

\int u^{10} d u = \frac{u ^{11}}{11}

= \frac{u ^{7}}{7} + \frac{2 u ^{9}}{9} + \frac{u ^{11}}{11}

Setze in

u = tan (x)

ein

= \frac{tan ^{7} ( x )}{7} + \frac{2 tan ^{9} ( x )}{9} + \frac{tan ^{11} ( x )}{11}
