integral from 1 to 3 of (2x+5)

Lösung

\int_{1}^{3} (2 x + 5) d x

18

Schritte zur Lösung

\int_{1}^{3} 2 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} 2 x d x + \int_{1}^{3} 5 d x

\int_{1}^{3} 2 x d x = 8

\int_{1}^{3} 5 d x = 10

= 8 + 10

Vereinfache

= 18

\int_{0}^{2 π} 2 cos^{2} (u) d u

\int_{0}^{8} \frac{x}{7 x + 2} d x

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

\int_{2}^{6} 8 t^{3} - 6 t^{- 2} d t

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