x (x - 1)^{4} : x^{5} - 4 x^{4} + 6 x^{3} - 4 x^{2} + x

= \int_{1}^{2} x^{5} - 4 x^{4} + 6 x^{3} - 4 x^{2} + x d x

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{1}^{2} x^{5} d x - \int_{1}^{2} 4 x^{4} d x + \int_{1}^{2} 6 x^{3} d x - \int_{1}^{2} 4 x^{2} d x + \int_{1}^{2} x d x

\int_{1}^{2} x^{5} d x = \frac{21}{2}

\int_{1}^{2} 4 x^{4} d x = \frac{124}{5}

\int_{1}^{2} 6 x^{3} d x = \frac{45}{2}

\int_{1}^{2} 4 x^{2} d x = \frac{28}{3}

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

= \frac{21}{2} - \frac{124}{5} + \frac{45}{2} - \frac{28}{3} + \frac{3}{2}

Vereinfache

\frac{21}{2} - \frac{124}{5} + \frac{45}{2} - \frac{28}{3} + \frac{3}{2} : \frac{11}{30}

= \frac{11}{30}

\int ln (t) \cdot t^{2} d t

x \to + (- \infty) + lim (x^{5})

\frac{d y}{d x} = \frac{5 x}{2 y}

a re a y = x^{- 3}, 1 \leq x \leq 6
