Use cases
- Write beta radiation or particle physics notation like β-decay.
- Reference the beta coefficient in finance, the measure of a stock's volatility against the market.
- Insert beta into statistical formulas, such as regression coefficients or Type II error rate.
- Type Greek letters in a physics or engineering report without a special keyboard layout.
- Copy the correct LaTeX command (\beta) for a paper or lab report instead of typing it from memory.
- Add beta to a plan or version label (Beta Release, v2 beta) using the real Greek character.
