integral of 1/2 x^2-2x+6

Lösung

\int \frac{1}{2} x^{2} - 2 x + 6 d x

\frac{x ^{3}}{6} - x^{2} + 6 x + C

Schritte zur Lösung

\int \frac{1}{2} x^{2} - 2 x + 6 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{1}{2} x^{2} d x - \int 2 x d x + \int 6 d x

\int \frac{1}{2} x^{2} d x = \frac{x ^{3}}{6}

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

\int 6 d x = 6 x

= \frac{x ^{3}}{6} - x^{2} + 6 x

Füge eine Konstante zur Lösung hinzu

= \frac{x ^{3}}{6} - x^{2} + 6 x + C
