integral from 0 to 1 of pi(x-x^4)^2

Lösung

\int_{0}^{1} π (x - x^{4})^{2} d x

Lösung

\frac{π}{9}

+1

Dezimale

0.34906 \dots

Schritte zur Lösung

\int_{0}^{1} π (x - x^{4})^{2} d x

Entferne die Konstante:

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

= π \cdot \int_{0}^{1} (x - x^{4})^{2} d x

Faktorisiere

x - x^{4} : - (- x + x^{4})

= π \cdot \int_{0}^{1} (- (- x + x^{4}))^{2} d x

Vereinfache

(- (- x + x^{4}))^{2} : (- x + x^{4})^{2}

= π \cdot \int_{0}^{1} (- x + x^{4})^{2} d x

Multipliziere aus

(- x + x^{4})^{2} : x^{2} - 2 x^{5} + x^{8}

= π \cdot \int_{0}^{1} x^{2} - 2 x^{5} + x^{8} 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

= π (\int_{0}^{1} x^{2} d x - \int_{0}^{1} 2 x^{5} d x + \int_{0}^{1} x^{8} d x)

\int_{0}^{1} x^{2} d x = \frac{1}{3}

\int_{0}^{1} 2 x^{5} d x = \frac{1}{3}

\int_{0}^{1} x^{8} d x = \frac{1}{9}

= π (\frac{1}{3} - \frac{1}{3} + \frac{1}{9})

Vereinfache

π (\frac{1}{3} - \frac{1}{3} + \frac{1}{9}) : \frac{π}{9}

= \frac{π}{9}
