Greek Alphabet

The symbols of the Greek Alphabet are used throughout math to represent variables, constants, and coeffecients within math expressions, formulas, and equations. This page first lists the lower case Greek symbols and their usage and then lists the upper case Greek symbols and their usage in math.

Symbol Description
alpha Symbol

The Greek letter (alpha) is used in math as a variable.

beta Symbol

The symbol is the lower case Greek letter beta. The symbol is used in mathematics as a variable.

chi Symbol

The Greek letter chi (χ).

delta Symbol

The greek lower case letter δ (delta) is used in mathematics as a variable.

epsilon Symbol

The Greek letter epsilon (ε).

eta Symbol

The Greek letter eta (η).

gamma Symbol

The Greek letter gamma (γ).

iota Symbol

The Greek letter ioata (ι).

kappa Symbol

The Greek letter kappa (κ).

lambda Symbol

The Greek letter lambda (λ) is a symbol used throughout mathematics, computer science, and physics. Lambda is used to represent the wavelength of a wave when discussing wave forms and equations. In computer science, the symbol is used in the study of “lambda calculus” and anonymous functions.

mu Symbol

The Greek letter mu (μ) is used in statistics to represent the population mean of a distribution.

nu Symbol

The Greek letter nu (ν).

omega Symbol

The Greek letter omega (ω).

omicron Symbol

The Greek letter omicron (ο).

phi Symbol

The Greek letter phi (φ) is used in geometry as a constant to represent the golden ratio.

pi Symbol

The Greek letter (pi) is used in trigonometry as a constant to represent a half-rotation around a circle in radians. The value of is approximately . The symbol appears in multiple geometric formulas.

psi Symbol

The Greek letter psi (ψ).

rho Symbol

The symbol is the lower case Greek letter rho (ρ). In mathematics the symbol is used as a variable. In physics, more specifically, the symbol is used to represent density.

tau Symbol

The Greek letter τ (tau) is used in trigonometry as a constant to represent a full rotation around a circle in radians. The value of τ is approximately 6.28 and can be calculated by dividing any circle's circumference by its radius.

theta Symbol

The Greek letter theta is used in mathematics as a variable usually associated with a measured angle. For example, the symbol theta appears in the three main trigonometric functions: sine, cosine, and tangent as the input variable.

In plain language, this represents the cosine function which takes in one argument represented by the variable .

xi Symbol

The Greek letter xi (ξ).

zeta Symbol

The Greek letter zeta (ζ).

Symbol Description
