希臘字母第八個（Θ/θ）

Θ (uppercase) and θ (lowercase) are the capital and small forms of the eighth character in the Greek writing system. This letter is widely used as a symbol in mathematics and science — for example, to label an unknown angle in geometry or to represent temperature in physics.

用法筆記

Pronounced /ˈθiːtə/ (THEE-tuh) in both American and British English. The 'th' sound at the start does not exist in Mandarin or many other Asian languages, so learners often need extra practice saying it. In mathematics, θ is routinely used to label an unknown angle in trigonometry and geometry. In physics, lowercase θ often stands for temperature or an angle, while uppercase Θ may represent a thermodynamic quantity.
