Integral von $$$\frac{_e a^{2} l t}{\nu}$$$ nach $$$t$$$

Bestimme $$$\int \frac{_e a^{2} l t}{\nu}\, dt$$$.

Wende die Konstantenfaktorregel $$$\int c f{\left(t \right)}\, dt = c \int f{\left(t \right)}\, dt$$$ mit $$$c=\frac{_e a^{2} l}{\nu}$$$ und $$$f{\left(t \right)} = t$$$ an:

$${\color{red}{\int{\frac{_e a^{2} l t}{\nu} d t}}} = {\color{red}{\frac{_e a^{2} l \int{t d t}}{\nu}}}$$

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

$$\frac{_e a^{2} l {\color{red}{\int{t d t}}}}{\nu}=\frac{_e a^{2} l {\color{red}{\frac{t^{1 + 1}}{1 + 1}}}}{\nu}=\frac{_e a^{2} l {\color{red}{\left(\frac{t^{2}}{2}\right)}}}{\nu}$$

Daher,

$$\int{\frac{_e a^{2} l t}{\nu} d t} = \frac{_e a^{2} l t^{2}}{2 \nu}$$

Fügen Sie die Integrationskonstante hinzu:

$$\int{\frac{_e a^{2} l t}{\nu} d t} = \frac{_e a^{2} l t^{2}}{2 \nu}+C$$

$$$\int \frac{_e a^{2} l t}{\nu}\, dt = \frac{_e a^{2} l t^{2}}{2 \nu} + C$$$A
