\int_{2}^{10} \frac{k}{x ^{3}} d x

\frac{3 k}{25}

Schritte zur Lösung

\int_{2}^{10} \frac{k}{x ^{3}} d x

Entferne die Konstante:

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

= k \cdot \int_{2}^{10} \frac{1}{x ^{3}} d x

Wende die Potenzregel an

= k [- \frac{1}{2 x ^{2}}]_{2}^{10}

Berechne die Grenzen:

\frac{3}{25}

= k \frac{3}{25}

Vereinfache

= \frac{3 k}{25}

\int_{- 1}^{0} 2 x^{2} (3 x^{3} + 1)^{5} d x

\int_{0}^{π^{2}} cos (x) d x

\int_{4}^{8} \frac{x ^{2}}{2} - 8 x + 30 d x

\int_{0}^{3} x^{2} + 3 x d x

\int_{- 1}^{4} \frac{4}{3 x ^{2}} d x
