integral of 3x^2-18

Lösung

\int 3 x^{2} - 18 d x

Lösung

x^{3} - 18 x + C

Schritte zur Lösung

\int 3 x^{2} - 18 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 3 x^{2} d x - \int 18 d x

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

\int 18 d x = 18 x

= x^{3} - 18 x

Füge eine Konstante zur Lösung hinzu

= x^{3} - 18 x + C
