$$$100000000 x$$$ 的积分
您的输入
求$$$\int 100000000 x\, dx$$$。
解答
对 $$$c=100000000$$$ 和 $$$f{\left(x \right)} = x$$$ 应用常数倍法则 $$$\int c f{\left(x \right)}\, dx = c \int f{\left(x \right)}\, dx$$$:
$${\color{red}{\int{100000000 x d x}}} = {\color{red}{\left(100000000 \int{x d x}\right)}}$$
应用幂法则 $$$\int x^{n}\, dx = \frac{x^{n + 1}}{n + 1}$$$ $$$\left(n \neq -1 \right)$$$,其中 $$$n=1$$$:
$$100000000 {\color{red}{\int{x d x}}}=100000000 {\color{red}{\frac{x^{1 + 1}}{1 + 1}}}=100000000 {\color{red}{\left(\frac{x^{2}}{2}\right)}}$$
因此,
$$\int{100000000 x d x} = 50000000 x^{2}$$
加上积分常数:
$$\int{100000000 x d x} = 50000000 x^{2}+C$$
答案
$$$\int 100000000 x\, dx = 50000000 x^{2} + C$$$A
