integral from-1 to 3 of (x^3-3x^2)

Lösung

\int_{- 1}^{3} (x^{3} - 3 x^{2}) d x

- 8

Schritte zur Lösung

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

\int_{- 1}^{3} x^{3} d x = 20

\int_{- 1}^{3} 3 x^{2} d x = 28

= 20 - 28

Vereinfache

= - 8

\int_{0}^{x^{2}} e^{- 2 t^{2}} d t

\int_{0}^{\frac{π}{3}} y ln (z) tan (x) d x

\int_{1}^{2} \frac{1 + x ^{2}}{x ^{4}} d x

\int_{- 2}^{0} x^{4} - 2 x^{2} d x

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