LaTeX Greek Letters and Common Math Symbols (Cheat Sheet)

Greek letters and a few operators show up constantly. Pattern: backslash + English name—\alpha, \beta, \pi, \Sigma. Look them up; don’t grind memorization.

Lowercase (common picks)

Letter	Command	Letter	Command
α	\alpha	θ	\theta
β	\beta	λ	\lambda
γ	\gamma	μ	\mu
δ	\delta	π	\pi
ε	\epsilon	σ	\sigma
φ	\phi	ω	\omega

Uppercase you’ll see often: \Gamma, \Delta, \Theta, \Lambda, \Pi, \Sigma, \Phi, \Omega.

Ops and relations

• Sum / product / integral: \sum, \prod, \int
• Limit: \lim_{x \to 0}
• Inequalities / approx: \neq, \leq, \geq, \approx
• Infinity: \infty

If a command won’t stick, click the symbol in the formula editor toolbar and read the LaTeX bar. Cheat sheet here; practice there.
