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

Wende U-Substitution an

= \int_{l n (2)}^{1} \frac{1}{u ^{2}} d u

Wende die Potenzregel an

= [- \frac{1}{u}]_{l n (2)}^{1}

Berechne die Grenzen:

- 1 + \frac{1}{ln ( 2 )}

= - 1 + \frac{1}{ln ( 2 )}

\int_{- 1}^{1} sec^{2} (x) d x

\int_{- 1}^{1} 1 + x^{3} d x

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

\int_{0}^{4} (2 x + 1)^{- \frac{1}{2}} d x

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