\int_{1}^{10} \frac{2 ln ( x )}{x} d x

Entferne die Konstante:

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

= 2 \cdot \int_{1}^{10} \frac{ln ( x )}{x} d x

Wende U-Substitution an

= 2 \cdot \int_{0}^{l n (10)} u d u

Wende die Potenzregel an

= 2 [\frac{u ^{2}}{2}]_{0}^{l n (10)}

Berechne die Grenzen:

\frac{ln ^{2} ( 10 )}{2}

= 2 \cdot \frac{ln ^{2} ( 10 )}{2}

Vereinfache

= ln^{2} (10)

\int_{1}^{3} 2^{2 x} d x

\int_{0}^{x^{2}} \frac{y}{x ^{5} + 1} d y

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

\int_{1}^{3} \frac{1}{x ^{2} + x} d x

\int_{27}^{64} 3 x d x
