Which Greek letter is used as a symbol in mathematics?
How many letters are in the Greek alphabet?
Why do mathematicians use the Greek alphabet?
Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities. In these contexts, the capital letters and the small letters represent distinct and unrelated entities.

- Alpha (α) First up, the lowercase Alpha is often used to represent alpha particles in physics. It has many other uses in sciences and engineering, including representing absorption factor, angles, angular acceleration, attenuation constant, common-base currentam pilifition factor, deviation of state parameter, temperature coefficient of resistance, thermal expansion coefficient, and thermal diffusivity.
- Beta (β) In physics, the lowercase Beta is used to denote a beta particle or beta ray, which is a high-energy and high-speed electron. It is also used to represent angles, common-emitter current-amplification factor, flux density, phase constant, and wavelength constant.
- Gamma (γ) You guessed it, another radiation letter: gamma radiation. This is one of the most common uses of this lowercase letter, while the uppercase letter is used to annotate a boundary limit when doing a 2D finite element analysis.
- Delta (Δ) Used in many engineering fields and physics, the uppercase Delta usually denotes the difference between any type of measurement. For example, if you want to find out the difference between length 1 and length 2, you would write it out as ΔL.

Mar 4, 2019 · The Greek Alphabet is used extensively in science and chemistry to represent variables and symbols. This table lists all twenty-four Greek letters.
History and Usage. The Greek alphabet has 24 letters, each with uppercase and lowercase forms. These letters are often used as symbols for constants, variables, and special functions in mathematical and scientific notation. Examples include α (alpha), β (beta), γ (gamma), δ (delta), and π (pi). Creating Greek Letters.
Greek symbols are used in math and science due to the fact that the Greek alphabet heavily influenced European mathematics. The Greek alphabet has 24 symbols, all of which can be written in...
