integral from 1 to 3 of (x+2)

Lösung

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

8

Schritte zur Lösung

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

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

\int_{1}^{3} 2 d x = 4

= 4 + 4

Vereinfache

= 8

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

\int_{- 1}^{1} \frac{1}{4 x ^{2} - 9} d x

\int_{3}^{8} \frac{x}{1 + x} d x

\int_{2}^{6} x x - 2 d x

\int_{0}^{2 π} (sin (x)) d x
