integral of (7x+cos(x))

Lösung

\int (7 x + cos (x)) d x

Lösung

\frac{7 x ^{2}}{2} + sin (x) + C

Schritte zur Lösung

\int 7 x + cos (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 7 x d x + \int cos (x) d x

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

\int cos (x) d x = sin (x)

= \frac{7 x ^{2}}{2} + sin (x)

Füge eine Konstante zur Lösung hinzu

= \frac{7 x ^{2}}{2} + sin (x) + C
