Where Greek letters show up
Greek letters are everywhere in maths, science and engineering: π for pi, Σ for a sum, Δ for change, λ for wavelength, μ for micro, Ω for ohms, θ for an angle. They also appear in statistics (σ, β), finance (alpha and beta, often written out), and as names for everything from fraternities to software releases. Each one here is a real Unicode character, so it copies cleanly into documents, equations and slides. If you need the matching mathematical operators (∑, √, ∞) to go with them, the math symbols page has those.
How do I type a specific Greek letter like pi or sigma?
The quickest way is to copy it above. In some tools you can also type the name and a shortcut — for example, in LaTeX \pi and \sigma produce the symbols, and Microsoft Word converts \pi then space via its equation tools.
What's the difference between lowercase σ and uppercase Σ?
They're different characters with different meanings by convention — lowercase σ often denotes standard deviation or a single value, while uppercase Σ denotes summation. Copy whichever your context needs.
