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

Lösung

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

16

Schritte zur Lösung

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

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

\int_{- 1}^{3} 1 d x = 4

= 20 - 4

= 16

\int_{0}^{2 π} 6 cos^{2} (x) d x

\int_{6}^{36} \frac{1}{x ( ln ( x ) ) ^{8}} d x

\int_{1}^{e^{x}} 9 ln (x) d x

\int_{3}^{5} \frac{1}{x - 4} d x

\int_{0}^{1} 5 x (1 - x)^{4} d x
