The Beta Symbol (β) in Science & Finance
The Beta symbol (β) is the lowercase second letter of the Greek alphabet. It is widely used across math, statistics, physics, and finance:
- Angles: Used in trigonometry alongside alpha to denote a secondary angle.
- Finance: Measures the volatility (systematic risk) of a stock relative to the overall market.
- Physics & Chemistry: Denotes beta radiation, beta particles, or beta-decay processes.
- Statistics: Represents the probability of a Type II error in hypothesis testing.
How to Use and Copy the Beta Sign Online
Copying the Beta symbol is fast. Click the Copy button on the card at the top. You can also write beta or the LaTeX command \beta, or draw the beta shape (resembling a sharp 'B' with a descender) on the canvas to find it.
Common Financial and Physics Equations
Beta is used in risk calculations and radioactive decay:
- CAPM Formula: $E(R_i) = R_f + \beta_i (E(R_m) - R_f)$ where $\beta$ represents asset volatility.
- Beta Minus Decay: $n \to p + e^- + \bar{\nu}_e$ where a neutron decays emitting a beta particle.
- Beta Function: $B(x, y) = \int_0^1 t^{x-1}(1-t)^{y-1}dt$ used in calculus.
