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

Vereinfache

= 10

\int_{0}^{2} (7 x^{2} - 3 x + 2) d x

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

\int_{0}^{2} (y + 3) d y

\int_{2}^{3} \frac{1}{x x ^{4} - 4} d x

\int_{5}^{\infty} ln (x) d x
