求$$$\int 4 x^{11} z^{6}\, dx$$$。
解答
套用常數倍法則 $$$\int c f{\left(x \right)}\, dx = c \int f{\left(x \right)}\, dx$$$,使用 $$$c=4 z^{6}$$$ 與 $$$f{\left(x \right)} = x^{11}$$$:
$${\color{red}{\int{4 x^{11} z^{6} d x}}} = {\color{red}{\left(4 z^{6} \int{x^{11} d x}\right)}}$$
套用冪次法則 $$$\int x^{n}\, dx = \frac{x^{n + 1}}{n + 1}$$$ $$$\left(n \neq -1 \right)$$$,以 $$$n=11$$$:
$$4 z^{6} {\color{red}{\int{x^{11} d x}}}=4 z^{6} {\color{red}{\frac{x^{1 + 11}}{1 + 11}}}=4 z^{6} {\color{red}{\left(\frac{x^{12}}{12}\right)}}$$
因此,
$$\int{4 x^{11} z^{6} d x} = \frac{x^{12} z^{6}}{3}$$
加上積分常數:
$$\int{4 x^{11} z^{6} d x} = \frac{x^{12} z^{6}}{3}+C$$
答案
$$$\int 4 x^{11} z^{6}\, dx = \frac{x^{12} z^{6}}{3} + C$$$A
