integral of 2x^2-8cos(x)

Lösung

\int 2 x^{2} - 8 cos (x) d x

Lösung

\frac{2 x ^{3}}{3} - 8 sin (x) + C

Schritte zur Lösung

\int 2 x^{2} - 8 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 2 x^{2} d x - \int 8 cos (x) d x

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

\int 8 cos (x) d x = 8 sin (x)

= \frac{2 x ^{3}}{3} - 8 sin (x)

Füge eine Konstante zur Lösung hinzu

= \frac{2 x ^{3}}{3} - 8 sin (x) + C
