Schritte zur Lösung

\int_{0}^{50} x^{2} - 50 x + 700 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_{0}^{50} x^{2} d x - \int_{0}^{50} 50 x d x + \int_{0}^{50} 700 d x

\int_{0}^{50} x^{2} d x = \frac{125000}{3}

\int_{0}^{50} 50 x d x = 62500

\int_{0}^{50} 700 d x = 35000

= \frac{125000}{3} - 62500 + 35000

Vereinfache

\frac{125000}{3} - 62500 + 35000 : \frac{42500}{3}

= \frac{42500}{3}

\int_{- 1}^{1} x cos^{3} (x) d x

\int_{- 5}^{1} - x^{2} - 3 x d x

\int_{0}^{1} 1 - x d x

\int_{1}^{x} \frac{1}{1 + t ^{3}} d t

\int_{- x}^{x} x + y d y
