\frac{1}{144} (36 x - \frac{x ^{3}}{3})

Schritte zur Lösung

\int_{0}^{x} \frac{36 - x ^{2}}{144} d x

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{144} \cdot \int_{0}^{x} 36 - 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

= \frac{1}{144} (\int_{0}^{x} 36 d x - \int_{0}^{x} x^{2} d x)

\int_{0}^{x} 36 d x = 36 x

\int_{0}^{x} x^{2} d x = \frac{x ^{3}}{3}

= \frac{1}{144} (36 x - \frac{x ^{3}}{3})

\int_{0}^{b} e^{- s t} t d t

\int_{6}^{8} 4 x + 50 e^{- 0.2 x} d x

\int_{0}^{2} 2 y^{2} d y

\int_{0}^{2} arctan (x) d x

\int_{- 1}^{- 1} 2 x d x
