$$$d$$$에 대한 $$$d \delta \cos^{4}{\left(\delta \right)}$$$의 적분

$$$\int d \delta \cos^{4}{\left(\delta \right)}\, dd$$$을(를) 구하시오.

상수배 법칙 $$$\int c f{\left(d \right)}\, dd = c \int f{\left(d \right)}\, dd$$$을 $$$c=\delta \cos^{4}{\left(\delta \right)}$$$와 $$$f{\left(d \right)} = d$$$에 적용하세요:

$${\color{red}{\int{d \delta \cos^{4}{\left(\delta \right)} d d}}} = {\color{red}{\delta \cos^{4}{\left(\delta \right)} \int{d d d}}}$$

멱법칙($$$\int d^{n}\, dd = \frac{d^{n + 1}}{n + 1}$$$ $$$\left(n \neq -1 \right)$$$)을 $$$n=1$$$에 적용합니다:

$$\delta \cos^{4}{\left(\delta \right)} {\color{red}{\int{d d d}}}=\delta \cos^{4}{\left(\delta \right)} {\color{red}{\frac{d^{1 + 1}}{1 + 1}}}=\delta \cos^{4}{\left(\delta \right)} {\color{red}{\left(\frac{d^{2}}{2}\right)}}$$

따라서,

$$\int{d \delta \cos^{4}{\left(\delta \right)} d d} = \frac{d^{2} \delta \cos^{4}{\left(\delta \right)}}{2}$$

적분 상수를 추가하세요:

$$\int{d \delta \cos^{4}{\left(\delta \right)} d d} = \frac{d^{2} \delta \cos^{4}{\left(\delta \right)}}{2}+C$$

$$$\int d \delta \cos^{4}{\left(\delta \right)}\, dd = \frac{d^{2} \delta \cos^{4}{\left(\delta \right)}}{2} + C$$$A
