Schritte zur Lösung

\int_{3}^{6} x^{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_{3}^{6} x^{2} d x + \int_{3}^{6} x d x

\int_{3}^{6} x^{2} d x = 63

\int_{3}^{6} x d x = \frac{27}{2}

= 63 + \frac{27}{2}

Vereinfache

63 + \frac{27}{2} : \frac{153}{2}

= \frac{153}{2}

\int_{- \infty}^{2} 6 e^{3 x} d x

\int_{0}^{1} \frac{1}{1 + e ^{- x}} d x

\int_{0}^{90} sin (x) d x

\int_{0}^{1} (e^{4 x} + 2 x^{2}) d x

\int_{0}^{\infty} e^{- 3 x^{2}} d x
