integral from-1 to 2 of (x^2+2)

Lösung

\int_{- 1}^{2} (x^{2} + 2) d x

9

Schritte zur Lösung

\int_{- 1}^{2} x^{2} + 2 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}^{2} x^{2} d x + \int_{- 1}^{2} 2 d x

\int_{- 1}^{2} x^{2} d x = 3

\int_{- 1}^{2} 2 d x = 6

= 3 + 6

\int_{0}^{1} 6 (1 - x) d x

\int_{0}^{1} y^{3} d y

\int_{- 4}^{2} x^{2} + 2 x - 8 d x

\int_{0}^{\frac{π}{6}} cos (2 x) d x

\int_{- \frac{π}{3}}^{\frac{π}{3}} tan (x) d x
