integral of sqrt(x^4-2x^3+x^2)

Lösung

\int x^{4} - 2 x^{3} + x^{2} d x

Lösung

\frac{x ^{3}}{3} - \frac{x ^{2}}{2} + C

Schritte zur Lösung

\int x^{4} - 2 x^{3} + x^{2} d x

Faktorisiere

x^{4} - 2 x^{3} + x^{2} : x^{2} (x - 1)^{2}

= \int x^{2} (x - 1)^{2} d x

Wende Exponentenregel an:

a^{n} \cdot b^{n} = (a \cdot b)^{n}

x^{2} (x - 1)^{2} = x^{2} (x - 1)^{2}

= \int x^{2} (x - 1)^{2} d x

Wende Exponentenregel an:

a^{n} \cdot b^{n} = (a \cdot b)^{n}

x^{2} (x - 1)^{2} = (x (x - 1))^{2}

= \int (x (x - 1))^{2} d x

(x (x - 1))^{2} = (x (x - 1)),

angenommen

x (x - 1) \geq 0

= \int x (x - 1) d x

x (x - 1) : x^{2} - x

= \int 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 x^{2} d x - \int x d x

\int x^{2} d x = \frac{x ^{3}}{3}

\int x d x = \frac{x ^{2}}{2}

= \frac{x ^{3}}{3} - \frac{x ^{2}}{2}
