$$$- \frac{8767 x^{2}}{10000} + \frac{8767 \sin{\left(x \right)}}{10000}$$$의 적분

$$$\int \left(- \frac{8767 x^{2}}{10000} + \frac{8767 \sin{\left(x \right)}}{10000}\right)\, dx$$$을(를) 구하시오.

각 항별로 적분하십시오:

$${\color{red}{\int{\left(- \frac{8767 x^{2}}{10000} + \frac{8767 \sin{\left(x \right)}}{10000}\right)d x}}} = {\color{red}{\left(- \int{\frac{8767 x^{2}}{10000} d x} + \int{\frac{8767 \sin{\left(x \right)}}{10000} d x}\right)}}$$

상수배 법칙 $$$\int c f{\left(x \right)}\, dx = c \int f{\left(x \right)}\, dx$$$을 $$$c=\frac{8767}{10000}$$$와 $$$f{\left(x \right)} = x^{2}$$$에 적용하세요:

$$\int{\frac{8767 \sin{\left(x \right)}}{10000} d x} - {\color{red}{\int{\frac{8767 x^{2}}{10000} d x}}} = \int{\frac{8767 \sin{\left(x \right)}}{10000} d x} - {\color{red}{\left(\frac{8767 \int{x^{2} d x}}{10000}\right)}}$$

멱법칙($$$\int x^{n}\, dx = \frac{x^{n + 1}}{n + 1}$$$ $$$\left(n \neq -1 \right)$$$)을 $$$n=2$$$에 적용합니다:

$$\int{\frac{8767 \sin{\left(x \right)}}{10000} d x} - \frac{8767 {\color{red}{\int{x^{2} d x}}}}{10000}=\int{\frac{8767 \sin{\left(x \right)}}{10000} d x} - \frac{8767 {\color{red}{\frac{x^{1 + 2}}{1 + 2}}}}{10000}=\int{\frac{8767 \sin{\left(x \right)}}{10000} d x} - \frac{8767 {\color{red}{\left(\frac{x^{3}}{3}\right)}}}{10000}$$

상수배 법칙 $$$\int c f{\left(x \right)}\, dx = c \int f{\left(x \right)}\, dx$$$을 $$$c=\frac{8767}{10000}$$$와 $$$f{\left(x \right)} = \sin{\left(x \right)}$$$에 적용하세요:

$$- \frac{8767 x^{3}}{30000} + {\color{red}{\int{\frac{8767 \sin{\left(x \right)}}{10000} d x}}} = - \frac{8767 x^{3}}{30000} + {\color{red}{\left(\frac{8767 \int{\sin{\left(x \right)} d x}}{10000}\right)}}$$

사인 함수의 적분은 $$$\int{\sin{\left(x \right)} d x} = - \cos{\left(x \right)}$$$:

$$- \frac{8767 x^{3}}{30000} + \frac{8767 {\color{red}{\int{\sin{\left(x \right)} d x}}}}{10000} = - \frac{8767 x^{3}}{30000} + \frac{8767 {\color{red}{\left(- \cos{\left(x \right)}\right)}}}{10000}$$

따라서,

$$\int{\left(- \frac{8767 x^{2}}{10000} + \frac{8767 \sin{\left(x \right)}}{10000}\right)d x} = - \frac{8767 x^{3}}{30000} - \frac{8767 \cos{\left(x \right)}}{10000}$$

간단히 하시오:

$$\int{\left(- \frac{8767 x^{2}}{10000} + \frac{8767 \sin{\left(x \right)}}{10000}\right)d x} = - \frac{8767 \left(x^{3} + 3 \cos{\left(x \right)}\right)}{30000}$$

적분 상수를 추가하세요:

$$\int{\left(- \frac{8767 x^{2}}{10000} + \frac{8767 \sin{\left(x \right)}}{10000}\right)d x} = - \frac{8767 \left(x^{3} + 3 \cos{\left(x \right)}\right)}{30000}+C$$

$$$\int \left(- \frac{8767 x^{2}}{10000} + \frac{8767 \sin{\left(x \right)}}{10000}\right)\, dx = - \frac{8767 \left(x^{3} + 3 \cos{\left(x \right)}\right)}{30000} + C$$$A
