Integral de $$$f r^{2} t^{2}$$$ con respecto a $$$t$$$

Halla $$$\int f r^{2} t^{2}\, dt$$$.

Aplica la regla del factor constante $$$\int c f{\left(t \right)}\, dt = c \int f{\left(t \right)}\, dt$$$ con $$$c=f r^{2}$$$ y $$$f{\left(t \right)} = t^{2}$$$:

$${\color{red}{\int{f r^{2} t^{2} d t}}} = {\color{red}{f r^{2} \int{t^{2} d t}}}$$

Aplica la regla de la potencia $$$\int t^{n}\, dt = \frac{t^{n + 1}}{n + 1}$$$ $$$\left(n \neq -1 \right)$$$ con $$$n=2$$$:

$$f r^{2} {\color{red}{\int{t^{2} d t}}}=f r^{2} {\color{red}{\frac{t^{1 + 2}}{1 + 2}}}=f r^{2} {\color{red}{\left(\frac{t^{3}}{3}\right)}}$$

Por lo tanto,

$$\int{f r^{2} t^{2} d t} = \frac{f r^{2} t^{3}}{3}$$

Añade la constante de integración:

$$\int{f r^{2} t^{2} d t} = \frac{f r^{2} t^{3}}{3}+C$$

$$$\int f r^{2} t^{2}\, dt = \frac{f r^{2} t^{3}}{3} + C$$$A
