integral of ((x^2)/3-8x-3)

Lösung

\int (\frac{x ^{2}}{3} - 8 x - 3) d x

\frac{x ^{3}}{9} - 4 x^{2} - 3 x + C

Schritte zur Lösung

\int \frac{x ^{2}}{3} - 8 x - 3 d x

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int \frac{x ^{2}}{3} d x - \int 8 x d x - \int 3 d x

\int \frac{x ^{2}}{3} d x = \frac{x ^{3}}{9}

\int 8 x d x = 4 x^{2}

\int 3 d x = 3 x

= \frac{x ^{3}}{9} - 4 x^{2} - 3 x

Füge eine Konstante zur Lösung hinzu

= \frac{x ^{3}}{9} - 4 x^{2} - 3 x + C

\int sin^{5} (x) cos^{9} (x) d x

\int \frac{x + 1}{x ^{2} + 10 x + 18} d x

\int \frac{1}{3 x ^{2} - 2 x + 5} d x

\int \frac{4 x ^{2}}{x ^{4} - 1} d x

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