Schritte zur Lösung

\int_{1}^{2} 2 x^{3} - x^{4} 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} 2 x^{3} d x - \int_{1}^{2} x^{4} d x

\int_{1}^{2} 2 x^{3} d x = \frac{15}{2}

\int_{1}^{2} x^{4} d x = \frac{31}{5}

= \frac{15}{2} - \frac{31}{5}

Vereinfache

\frac{15}{2} - \frac{31}{5} : \frac{13}{10}

= \frac{13}{10}

\int_{0}^{1} x (e^{x}) d x

\int_{1}^{3} y^{2} d y

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

\int_{0}^{1} 7 + 4 t^{2} d t

\int_{0}^{2} y (2 y^{2} - \frac{y ^{2}}{2}) d y
