Mathematical Notation and Cheatsheet

Understanding mathematical notation is useful to read papers and also be able to write your own equations and understanding of a problem. In this tutorial we will work on walking through understanding the Greek Alphabet, then notation for mathematical operations, and then using LaTex to write equations.

Greek Alphabet

Symbol	Name	Latex
Α α	Alpha	\alpha
Β β	Beta	\beta
Γ γ	Gamma	\gamma
Δ δ	Delta	\delta
Ε ε	Epsilon	\epsilon
Ζ ζ	Zeta	\zeta
Ι ι	Iota	\iota
Κ κ	Kappa	\kappa
Λ λ	Lambda	\lambda
Μ μ	Mu	\mu
Ν ν	Nu	\nu
Ξ ξ	Xi	\Xi
Ο ο	Omicron	\omicron
Π π	Pi	\pi
Ρ ρ	rho	\rho
Τ τ	Tau	\tau
Υ υ	Upsilon	\upsilon
Φ φ	Phi	\phi
Ψ ψ	Psi	\psi
Ω ω	Omega	\omega

Mathematical Operations

Equality/Similarity

''''

Symbol	Name	LaTex	Example
=	Equality	=	x=y if x and y = 1
≠	Inequality	\ne	x≠y if x = 0 and y = 1
≈	Approximation		pi≈3.14
≡	Identity
<	Less Than		x <y
≤	Less Than or Equal to		x≤y
≺	Precedes		x≺y
≻	Succeeds		x≻y
