integral of (2x+5)(x+1)^{1/2}

Lösung

\int (2 x + 5) (x + 1)^{\frac{1}{2}} d x

\frac{2}{3} (2 x + 5) (x + 1)^{\frac{3}{2}} - \frac{8}{15} (x + 1)^{\frac{5}{2}} + C

Schritte zur Lösung

\int (2 x + 5) (x + 1)^{\frac{1}{2}} d x

Wende die partielle Integration an

= \frac{2}{3} (2 x + 5) (x + 1)^{\frac{3}{2}} - \int \frac{4}{3} (x + 1)^{\frac{3}{2}} d x

\int \frac{4}{3} (x + 1)^{\frac{3}{2}} d x = \frac{8}{15} (x + 1)^{\frac{5}{2}}

= \frac{2}{3} (2 x + 5) (x + 1)^{\frac{3}{2}} - \frac{8}{15} (x + 1)^{\frac{5}{2}}
