常见用途

Omega (Capital) 符号通常用于以下情况:

Electrical Resistance

Symbol for ohms (electrical resistance).

Code

Resistance: $R = 100\Omega$

Output

Resistance: R = 100Ω

Sample Space

Used for the sample space in probability.

Code

Sample space: $\Omega = \{H, T\}$

Output

Sample space: Ω = {H, T}

常见问题

我应该使用哪种方法?

我们建议使用上面标记为"推荐"的方法。但是,最佳方法取决于您的具体需求:

  • \Omega: Uppercase Omega - ohm or sample space

我在哪里使用这个符号?

该符号可以用于:

  • 在数学方程式中(数学模式)
  • 在常规文本中(如果使用文本模式)
  • 在各种文档环境中

我可以在显示模式中使用这个吗?

是的,在数学模式($ $)中工作的符号也适用于显示模式($$ $$)。这允许您在自己的行上显示符号,具有更大的格式。
