integral of 22tan^6(x)

Lösung

\int 22 tan^{6} (x) d x

Lösung

22 (\frac{tan ^{5} ( x )}{5} - \frac{tan ^{3} ( x )}{3} + tan (x) - arctan (tan (x))) + C

Schritte zur Lösung

\int 22 tan^{6} (x) d x

Entferne die Konstante:

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

= 22 \cdot \int tan^{6} (x) d x

Wende U-Substitution an

= 22 \cdot \int \frac{u ^{6}}{1 + u ^{2}} d u

Lange Division

\frac{u ^{6}}{1 + u ^{2}} : u^{4} - u^{2} + 1 - \frac{1}{u ^{2} + 1}

= 22 \cdot \int u^{4} - u^{2} + 1 - \frac{1}{u ^{2} + 1} 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

= 22 (\int u^{4} d u - \int u^{2} d u + \int 1 d u - \int \frac{1}{u ^{2} + 1} d u)

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

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

\int 1 d u = u

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

= 22 (\frac{u ^{5}}{5} - \frac{u ^{3}}{3} + u - arctan (u))

Setze in

u = tan (x)

ein

= 22 (\frac{tan ^{5} ( x )}{5} - \frac{tan ^{3} ( x )}{3} + tan (x) - arctan (tan (x)))

= 22 (\frac{tan ^{5} ( x )}{5} - \frac{tan ^{3} ( x )}{3} + tan (x) - arctan (tan (x))) + C
