\int_{0}^{1} \frac{x}{1 - x ^{2}} d x

Wende U-Substitution an

= \int_{1}^{0} - \frac{1}{2 u} d u

\int_{a}^{b} f (x) d x = - \int_{b}^{a} f (x) d x, a < b

= - \int_{0}^{1} - \frac{1}{2 u} d u

Entferne die Konstante:

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

= - (- \frac{1}{2} \cdot \int_{0}^{1} \frac{1}{u} d u)

Wende die Potenzregel an

= - (- \frac{1}{2} [2 u^{\frac{1}{2}}]_{0}^{1})

Vereinfache

- (- \frac{1}{2} [2 u^{\frac{1}{2}}]_{0}^{1}) : \frac{1}{2} [2 u]_{0}^{1}

= \frac{1}{2} [2 u]_{0}^{1}

\frac{x d y}{d x} = 5 x e^{x} - y + 6 x^{2}

\int (x^{5} - 4 x)^{2} (5 x^{4} - 4) d x
