Mathematica 中的指数函数为 `Exp[x]`,其中 `x` 为指数。例如,`Exp[2]` 表示 $e^2$。如果指数为变量,可以使用如下方式表示:
- `Exp[x]`: $e^x$
- `Exp[-x]`: $e^{-x}$
- `Exp[2x]`: $e^{2x}$
- `Exp[x^2]`: $e^{x^2}$
- `Exp[2x+1]`: $e^{2x+1}$
还可以进行复合运算,例如:
- `Exp[x]^2`: $(e^x)^2=e^{2x}$
- `Exp[2x]/Exp[x]`: $\frac{e^{2x}}{e^x}=e^x$
- `Exp[x+1]/Exp[x-1]`: $\frac{e^{x+1}}{e^{x-1}}=e^2$
除了 `Exp[x]`,还有其他指数函数,例如:
- `E^x`: $e^x$
- `Power[E,x]`: $e^x$
- `ExpIntegralEi[x]`: $\int_{-\infty}^x \frac{e^t}{t} dt$ (指数积分函数)
需要注意的是,指数函数在 Mathemtica 中默认使用的是自然常数 $e$,而不是其他常数。
