Integral von $$$- \frac{x^{2}}{y^{2}}$$$ nach $$$x$$$

Bestimme $$$\int \left(- \frac{x^{2}}{y^{2}}\right)\, dx$$$.

Wende die Konstantenfaktorregel $$$\int c f{\left(x \right)}\, dx = c \int f{\left(x \right)}\, dx$$$ mit $$$c=- \frac{1}{y^{2}}$$$ und $$$f{\left(x \right)} = x^{2}$$$ an:

$${\color{red}{\int{\left(- \frac{x^{2}}{y^{2}}\right)d x}}} = {\color{red}{\left(- \frac{\int{x^{2} d x}}{y^{2}}\right)}}$$

Wenden Sie die Potenzregel $$$\int x^{n}\, dx = \frac{x^{n + 1}}{n + 1}$$$ $$$\left(n \neq -1 \right)$$$ mit $$$n=2$$$ an:

$$- \frac{{\color{red}{\int{x^{2} d x}}}}{y^{2}}=- \frac{{\color{red}{\frac{x^{1 + 2}}{1 + 2}}}}{y^{2}}=- \frac{{\color{red}{\left(\frac{x^{3}}{3}\right)}}}{y^{2}}$$

Daher,

$$\int{\left(- \frac{x^{2}}{y^{2}}\right)d x} = - \frac{x^{3}}{3 y^{2}}$$

Fügen Sie die Integrationskonstante hinzu:

$$\int{\left(- \frac{x^{2}}{y^{2}}\right)d x} = - \frac{x^{3}}{3 y^{2}}+C$$

$$$\int \left(- \frac{x^{2}}{y^{2}}\right)\, dx = - \frac{x^{3}}{3 y^{2}} + C$$$A
