Schritte zur Lösung

\int_{- 3}^{5} 2 y - (y^{2} - 15) d y

Vereinfache

= \int_{- 3}^{5} 2 y - y^{2} + 15 d y

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{- 3}^{5} 2 y d y - \int_{- 3}^{5} y^{2} d y + \int_{- 3}^{5} 15 d y

\int_{- 3}^{5} 2 y d y = 16

\int_{- 3}^{5} y^{2} d y = \frac{152}{3}

\int_{- 3}^{5} 15 d y = 120

= 16 - \frac{152}{3} + 120

Vereinfache

16 - \frac{152}{3} + 120 : \frac{256}{3}

= \frac{256}{3}

2 x^{\frac{3}{2}}

y^{^{'}} = \frac{( y - y ^{2} ) t}{1 + t ^{2}}

\int 2 x sin (2 x) d x
