integral from-2 to 4 of 2+x^2

Lösung

\int_{- 2}^{4} 2 + x^{2} d x

36

Schritte zur Lösung

\int_{- 2}^{4} 2 + 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_{- 2}^{4} 2 d x + \int_{- 2}^{4} x^{2} d x

\int_{- 2}^{4} 2 d x = 12

\int_{- 2}^{4} x^{2} d x = 24

= 12 + 24

Vereinfache

= 36

\int_{0}^{1} x e^{4 x} d x

\int_{0}^{6} (2 x - 1)^{2} d x

\int_{100}^{\infty} \frac{1}{x ^{2}} d x

\int_{x}^{8} t^{6} d t

\int_{0}^{1} 1 + x^{2} e^{x} d x
