integral of (cot(2t))^5

Lösung

\int (cot (2 t))^{5} d t

Lösung

- \frac{1}{2} (- \frac{1}{2} cot^{2} (2 t) + \frac{1}{4} cot^{4} (2 t) + \frac{1}{2} ln (csc^{2} (2 t))) + C

Schritte zur Lösung

\int (cot (2 t))^{5} d t

Vereinfache

= \int cot^{5} (2 t) d t

Wende U-Substitution an

= \int cot^{5} (u) \frac{1}{2} d u

Entferne die Konstante:

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

= \frac{1}{2} \cdot \int cot^{5} (u) d u

Wende U-Substitution an

= \frac{1}{2} \cdot \int - \frac{v ^{5}}{1 + v ^{2}} d v

Entferne die Konstante:

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

= \frac{1}{2} (- \int \frac{v ^{5}}{1 + v ^{2}} d v)

Lange Division

\frac{v ^{5}}{1 + v ^{2}} : v^{3} - v + \frac{v}{v ^{2} + 1}

= \frac{1}{2} (- \int v^{3} - v + \frac{v}{v ^{2} + 1} 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

= \frac{1}{2} (- (\int v^{3} d v - \int v d v + \int \frac{v}{v ^{2} + 1} d v))

\int v^{3} d v = \frac{v ^{4}}{4}

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

\int \frac{v}{v ^{2} + 1} d v = \frac{1}{2} ln v^{2} + 1

= \frac{1}{2} (- (\frac{v ^{4}}{4} - \frac{v ^{2}}{2} + \frac{1}{2} ln v^{2} + 1))

Ersetze zurück

= \frac{1}{2} (- (\frac{cot ^{4} ( 2 t )}{4} - \frac{cot ^{2} ( 2 t )}{2} + \frac{1}{2} ln cot^{2} (2 t) + 1))

Vereinfache

\frac{1}{2} (- (\frac{cot ^{4} ( 2 t )}{4} - \frac{cot ^{2} ( 2 t )}{2} + \frac{1}{2} ln cot^{2} (2 t) + 1)) : - \frac{1}{2} (- \frac{1}{2} cot^{2} (2 t) + \frac{1}{4} cot^{4} (2 t) + \frac{1}{2} ln (csc^{2} (2 t)))

= - \frac{1}{2} (- \frac{1}{2} cot^{2} (2 t) + \frac{1}{4} cot^{4} (2 t) + \frac{1}{2} ln (csc^{2} (2 t)))

Füge eine Konstante zur Lösung hinzu
