integral from 5 to x of 2/5-1/25 x

Lösung

\int_{5}^{x} \frac{2}{5} - \frac{1}{25} x d x

\frac{2 x}{5} - 2 - \frac{x ^{2} - 25}{50}

Schritte zur Lösung

\int_{5}^{x} \frac{2}{5} - \frac{1}{25} x 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_{5}^{x} \frac{2}{5} d x - \int_{5}^{x} \frac{1}{25} x d x

\int_{5}^{x} \frac{2}{5} d x = \frac{2 x}{5} - 2

\int_{5}^{x} \frac{1}{25} x d x = \frac{x ^{2} - 25}{50}

= \frac{2 x}{5} - 2 - \frac{x ^{2} - 25}{50}

\int_{3}^{8} x d x

\int_{0}^{π} x (sin (x)) d x

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

\int_{1}^{2} \frac{e ^{\frac{1}{x}}}{x ^{3}} d x

\int_{- 2}^{2} (x^{2} - 2) d x
