一些常见的微分公式如下(其中$f$和$g$是可微函数,$k$是常数): | |
1. 导数定义式:$\displaystyle f'(x) = \lim_{h\to0}\frac{f(x+h)-f(x)}{h}$ | |
2. 幂规则:$(x^k)' = kx^{k-1}$ | |
3. 和差规则:$(f+g)' = f'+g'$,$(f-g)'=f'-g'$ | |
4. 积规则:$(fg)' = f'g + fg'$ | |
5. 商规则:$\left(\frac{f}{g}\right)' = \frac{f'g - fg'}{g^2}$ | |
6. 链式法则:$\displaystyle (f(g(x)))' = f'(g(x))g'(x)$ | |
一个使用Golang语言编写的HelloWorld程序如下: | |
```go | |
package main | |
import "fmt" | |
func main() { | |
fmt.Println("Hello, world!") | |
} | |
``` | |
运行结果为: | |
``` | |
Hello, world! | |
``` | |
