integral of (1+3x)

Lösung

\int (1 + 3 x) d x

Lösung

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

Schritte zur Lösung

\int 1 + 3 x 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 1 d x + \int 3 x d x

\int 1 d x = x

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

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

Füge eine Konstante zur Lösung hinzu

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