integral from 0 to 3 of (x^2+2x)

Lösung

\int_{0}^{3} (x^{2} + 2 x) d x

18

Schritte zur Lösung

\int_{0}^{3} x^{2} + 2 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_{0}^{3} x^{2} d x + \int_{0}^{3} 2 x d x

\int_{0}^{3} x^{2} d x = 9

\int_{0}^{3} 2 x d x = 9

= 9 + 9

\int_{0}^{\frac{π}{4}} (cos (x))^{2} d x

\int_{- 2 π}^{2 π} \frac{π - x}{2} d x

\int_{4}^{6} \frac{2}{( x - 3 ) ^{2}} d x

\int_{- 5}^{- 2} \frac{x}{( x ^{2} + 3 ) ^{2}} d x

\int_{2}^{5} (6 x^{2} + 4 y - 3 y^{2}) d y
