Schritte zur Lösung

\int_{- 1}^{0} 4 x^{2} - x - \frac{1}{3} 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}^{0} 4 x^{2} d x - \int_{- 1}^{0} x d x - \int_{- 1}^{0} \frac{1}{3} d x

\int_{- 1}^{0} 4 x^{2} d x = \frac{4}{3}

\int_{- 1}^{0} x d x = - \frac{1}{2}

\int_{- 1}^{0} \frac{1}{3} d x = \frac{1}{3}

= \frac{4}{3} - (- \frac{1}{2}) - \frac{1}{3}

Vereinfache

\frac{4}{3} - (- \frac{1}{2}) - \frac{1}{3} : \frac{3}{2}

= \frac{3}{2}

\int_{100}^{120} - 0.00006 x^{2} + 6 d x

\int_{0}^{π} (cos (x) + 4)^{2} d x

\int_{- 2}^{0} e^{- x} d x

\int_{0}^{x} \frac{y}{1 + y ^{4}} d y

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