Dezimale

- 4.5

Schritte zur Lösung

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

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

\int_{- 1}^{2} 2 d x = 6

= \frac{3}{2} - 6

Vereinfache

\frac{3}{2} - 6 : - \frac{9}{2}

= - \frac{9}{2}

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

\int_{- π}^{0} cos (n) x d x

\int_{0}^{5} x^{2} + 2 x - 3 d x

\int_{0}^{1} 0.5 e^{x^{2}} d x

\int_{0}^{1} cos (nπ t) d t
