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

Wende U-Substitution an

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

Wende die Potenzregel an

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

Berechne die Grenzen:

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

= \frac{ln ^{2} ( 2 e )}{2}

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

\int_{0}^{x} 4 x d x

\int_{0}^{2 π} 2 sin (x) cos (x) d x

\int_{0}^{\frac{π}{2}} 1 + sin (x) d x

\int_{0}^{2 π} sin (x) cos (n x) d x
