integral from 0 to y of (r^2-(r^3)/x)

Lösung

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

- \frac{y ^{4}}{4 x} + \frac{y ^{3}}{3}

Schritte zur Lösung

\int_{0}^{y} r^{2} - \frac{r ^{3}}{x} d r

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}^{y} \frac{r ^{3}}{x} d r + \int_{0}^{y} r^{2} d r

\int_{0}^{y} \frac{r ^{3}}{x} d r = \frac{y ^{4}}{4 x}

\int_{0}^{y} r^{2} d r = \frac{y ^{3}}{3}

= - \frac{y ^{4}}{4 x} + \frac{y ^{3}}{3}

\int_{0}^{\infty} e^{- λ t} d t

\int_{1}^{\infty} \frac{1}{x ln ( x ) ln ( ln ( x ) )} d x

\int_{- 10 π}^{10 π} cos (x) d x

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

\int_{- 1}^{3} (∣ 2 - x ∣ + x^{2}) d x
