integral of x(4+x^2)^{10}

Lösung

\int x (4 + x^{2})^{10} d x

Lösung

\frac{1}{22} (4 + x^{2})^{11} + C

Schritte zur Lösung

\int x (4 + x^{2})^{10} d x

Wende U-Substitution an

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

Wende die Potenzregel an

= \frac{1}{2} \cdot \frac{u ^{11}}{11}

Setze in

u = 4 + x^{2}

ein

= \frac{1}{2} \cdot \frac{( 4 + x ^{2} ) ^{11}}{11}

Vereinfache

\frac{1}{2} \cdot \frac{( 4 + x ^{2} ) ^{11}}{11} : \frac{1}{22} (4 + x^{2})^{11}

= \frac{1}{22} (4 + x^{2})^{11}

Füge eine Konstante zur Lösung hinzu

= \frac{1}{22} (4 + x^{2})^{11} + C
