Zeta Symbol
About Zeta Symbol
Ζ is the Zeta Symbol, the sixth letter of the Greek alphabet in its uppercase form. Ζ denotes the Riemann zeta function in number theory and the damping ratio in engineering.
【Pronunciation】 In English, Ζ is most often pronounced ZEE-tuh (IPA: /ˈziːtə/). This is simply the anglicized name of the Greek letter.
The uppercase Zeta Symbol Ζ is written as a distinct capital Greek glyph and is assigned codepoint U+0396 in the Greek and Coptic Unicode block. In plain or sans-serif fonts it can be mistaken for the Latin letter Z, so verify the typeface or context.
【Historical Origin】 Like every Greek letter, Ζ was adapted from a Phoenician consonant and entered mathematical and scientific notation through the work of ancient Greek scholars, remaining in continuous use to the present day.
【Common Uses】 Ζ is highly active across disciplines and frequently appears alongside other Greek capitals such as Δ (Δ), Σ (Σ), Π (Π) and Ω (Ω) in formulas, papers, and engineering drawings. Its clear shape and long tradition make it a standard symbol in many fields.
