Integral de $$$a \epsilon \sigma t^{4}$$$ em relação a $$$t$$$

Encontre $$$\int a \epsilon \sigma t^{4}\, dt$$$.

Aplique a regra do múltiplo constante $$$\int c f{\left(t \right)}\, dt = c \int f{\left(t \right)}\, dt$$$ usando $$$c=a \epsilon \sigma$$$ e $$$f{\left(t \right)} = t^{4}$$$:

$${\color{red}{\int{a \epsilon \sigma t^{4} d t}}} = {\color{red}{a \epsilon \sigma \int{t^{4} d t}}}$$

Aplique a regra da potência $$$\int t^{n}\, dt = \frac{t^{n + 1}}{n + 1}$$$ $$$\left(n \neq -1 \right)$$$ com $$$n=4$$$:

$$a \epsilon \sigma {\color{red}{\int{t^{4} d t}}}=a \epsilon \sigma {\color{red}{\frac{t^{1 + 4}}{1 + 4}}}=a \epsilon \sigma {\color{red}{\left(\frac{t^{5}}{5}\right)}}$$

Portanto,

$$\int{a \epsilon \sigma t^{4} d t} = \frac{a \epsilon \sigma t^{5}}{5}$$

Adicione a constante de integração:

$$\int{a \epsilon \sigma t^{4} d t} = \frac{a \epsilon \sigma t^{5}}{5}+C$$

$$$\int a \epsilon \sigma t^{4}\, dt = \frac{a \epsilon \sigma t^{5}}{5} + C$$$A
