Lösung

\int 5 x^{4} + \frac{2}{3} x^{3} + \frac{7}{3} x^{2} - 16 x - \frac{4}{9} d x

x^{5} + \frac{x ^{4}}{6} + \frac{7 x ^{3}}{9} - 8 x^{2} - \frac{4}{9} x + C

Schritte zur Lösung

\int 5 x^{4} + \frac{2}{3} x^{3} + \frac{7}{3} x^{2} - 16 x - \frac{4}{9} 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 5 x^{4} d x + \int \frac{2}{3} x^{3} d x + \int \frac{7}{3} x^{2} d x - \int 16 x d x - \int \frac{4}{9} d x

\int 5 x^{4} d x = x^{5}

\int \frac{2}{3} x^{3} d x = \frac{x ^{4}}{6}

\int \frac{7}{3} x^{2} d x = \frac{7 x ^{3}}{9}

\int 16 x d x = 8 x^{2}

\int \frac{4}{9} d x = \frac{4}{9} x

= x^{5} + \frac{x ^{4}}{6} + \frac{7 x ^{3}}{9} - 8 x^{2} - \frac{4}{9} x

= x^{5} + \frac{x ^{4}}{6} + \frac{7 x ^{3}}{9} - 8 x^{2} - \frac{4}{9} x + C

\int 2 y - y^{2} d y

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

\int x x^{2} + 11 d x

\int x \cdot x^{2} + 4 d x

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