\int_{1}^{e^{2}} x^{4} ln (x) d x

Wende die partielle Integration an

= [\frac{1}{5} (x^{5} ln (x) - 5 \cdot \int \frac{x ^{4}}{5} d x)]_{1}^{e^{2}}

\int \frac{x ^{4}}{5} d x = \frac{x ^{5}}{25}

= [\frac{1}{5} (x^{5} ln (x) - 5 \cdot \frac{x ^{5}}{25})]_{1}^{e^{2}}

5 \cdot \frac{x ^{5}}{25} = \frac{x ^{5}}{5}

= [\frac{1}{5} (x^{5} ln (x) - \frac{x ^{5}}{5})]_{1}^{e^{2}}

Berechne die Grenzen:

\frac{9 e ^{10}}{25} + \frac{1}{25}

= \frac{9 e ^{10}}{25} + \frac{1}{25}

Vereinfache

= \frac{9 e ^{10} + 1}{25}

\int 5 x e^{- 3 x} d x

\frac{d y}{d x} = x + 9

x \to 2 - lim (\frac{x}{x ^{2} - 4})

f (x) = \frac{1}{x ^{2} - 9}

\frac{d}{d x} (\frac{2}{2})
