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

Lösung

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

10

Schritte zur Lösung

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

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

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

= 2 + 8

= 10

\int_{1}^{x} t d t

\int_{0}^{\frac{π}{2}} sin (\frac{x}{2}) d x

\int_{0}^{4} \frac{x ^{3}}{8} d x

\int_{0}^{1} x (x^{2} + 5) d x

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