integral from 1 to 3 of kx^2-2

Lösung

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

\frac{26 k}{3} - 4

Schritte zur Lösung

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

\int_{1}^{3} k x^{2} d x = \frac{26 k}{3}

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

= \frac{26 k}{3} - 4

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

\int_{0}^{π} t sin (2 t) d t

\int_{2}^{6} (3 + 2 x) d x

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

\int_{1}^{12} 4 e^{0.1 x} d x
