integral of (x+3)^{50}x

Lösung

\int (x + 3)^{50} x d x

Lösung

\frac{( x + 3 ) ^{52}}{52} - \frac{( x + 3 ) ^{51}}{17} + C

Schritte zur Lösung

\int (x + 3)^{50} x d x

Wende U-Substitution an

= \int (u - 3) u^{50} d u

Multipliziere aus

(u - 3) u^{50} : u^{51} - 3 u^{50}

= \int u^{51} - 3 u^{50} 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^{51} d u - \int 3 u^{50} d u

\int u^{51} d u = \frac{u ^{52}}{52}

\int 3 u^{50} d u = \frac{u ^{51}}{17}

= \frac{u ^{52}}{52} - \frac{u ^{51}}{17}

Setze in

u = x + 3

ein

= \frac{( x + 3 ) ^{52}}{52} - \frac{( x + 3 ) ^{51}}{17}

Füge eine Konstante zur Lösung hinzu

= \frac{( x + 3 ) ^{52}}{52} - \frac{( x + 3 ) ^{51}}{17} + C
