Integral von $$$\frac{\sqrt{2} x^{2} x_{1}}{2 \sqrt{\pi} e^{\frac{1}{2}}}$$$ nach $$$x$$$

Bestimme $$$\int \frac{\sqrt{2} x^{2} x_{1}}{2 \sqrt{\pi} e^{\frac{1}{2}}}\, dx$$$.

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

$${\color{red}{\int{\frac{\sqrt{2} x^{2} x_{1}}{2 \sqrt{\pi} e^{\frac{1}{2}}} d x}}} = {\color{red}{\left(\frac{\sqrt{2} x_{1} \int{x^{2} d x}}{2 \sqrt{\pi} e^{\frac{1}{2}}}\right)}}$$

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

$$\frac{\sqrt{2} x_{1} {\color{red}{\int{x^{2} d x}}}}{2 \sqrt{\pi} e^{\frac{1}{2}}}=\frac{\sqrt{2} x_{1} {\color{red}{\frac{x^{1 + 2}}{1 + 2}}}}{2 \sqrt{\pi} e^{\frac{1}{2}}}=\frac{\sqrt{2} x_{1} {\color{red}{\left(\frac{x^{3}}{3}\right)}}}{2 \sqrt{\pi} e^{\frac{1}{2}}}$$

Daher,

$$\int{\frac{\sqrt{2} x^{2} x_{1}}{2 \sqrt{\pi} e^{\frac{1}{2}}} d x} = \frac{\sqrt{2} x^{3} x_{1}}{6 \sqrt{\pi} e^{\frac{1}{2}}}$$

Fügen Sie die Integrationskonstante hinzu:

$$\int{\frac{\sqrt{2} x^{2} x_{1}}{2 \sqrt{\pi} e^{\frac{1}{2}}} d x} = \frac{\sqrt{2} x^{3} x_{1}}{6 \sqrt{\pi} e^{\frac{1}{2}}}+C$$

$$$\int \frac{\sqrt{2} x^{2} x_{1}}{2 \sqrt{\pi} e^{\frac{1}{2}}}\, dx = \frac{\sqrt{2} x^{3} x_{1}}{6 \sqrt{\pi} e^{\frac{1}{2}}} + C$$$A
