integral from 0 to 2 of 15x^2+14x-8

Lösung

\int_{0}^{2} 15 x^{2} + 14 x - 8 d x

52

Schritte zur Lösung

\int_{0}^{2} 15 x^{2} + 14 x - 8 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}^{2} 15 x^{2} d x + \int_{0}^{2} 14 x d x - \int_{0}^{2} 8 d x

\int_{0}^{2} 15 x^{2} d x = 40

\int_{0}^{2} 14 x d x = 28

\int_{0}^{2} 8 d x = 16

= 40 + 28 - 16

Vereinfache

= 52

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

\int_{0}^{1} x (3 x^{2}) d x

\int_{0}^{16} x d x

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

\int_{2}^{2} 1 + t^{3} d t
