Schritte zur Lösung

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

\int_{1}^{2} x^{2} d x = \frac{7}{3}

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

= \frac{7}{3} - \frac{3}{2}

Vereinfache

\frac{7}{3} - \frac{3}{2} : \frac{5}{6}

= \frac{5}{6}

\frac{d}{d x} (tan (1 + x^{3}))

\int_{1}^{2} \frac{13}{x ^{3} + 5 x} d x

\int 12 - 3 x^{2} d x

\int (3 - 2 t + t^{2}) d t

\int \frac{sin ( x )}{5 + cos ( x )} d x
