integral from-1 to 3 of (3x-5)

Lösung

\int_{- 1}^{3} (3 x - 5) d x

- 8

Schritte zur Lösung

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

\int_{- 1}^{3} 3 x d x = 12

\int_{- 1}^{3} 5 d x = 20

= 12 - 20

Vereinfache

= - 8

\int_{4}^{e^{x}} (y^{5} sin (y)) d y

\int_{- 1}^{2} y d y

\int_{0}^{x} λ e^{- λ x} d x

\int_{0}^{8} \frac{1}{1 + 1 + x} d x

\int_{0}^{1} x^{3} (2 + x^{4})^{3} d x
