Tau (/ ˈ t ɔː, ˈ t ɒ, ˈ t aʊ /; [1] uppercase Τ, lowercase τ or ; Greek: ταυ) is the nineteenth letter of the Greek alphabet, representing the voiceless dental or alveolar plosive IPA:. In the system of Greek numerals , it has a value of 300.
In the tau's case, this is the "antitau" (also called the positive tau). Tau particles are denoted by the symbol τ − and the antitaus by τ +. Tau leptons have a lifetime of 2.9 × 10 −13 s and a mass of 1 776.9 MeV /c 2 (compared to 105.66 MeV /c 2 for muons and 0.511 MeV /c 2 for electrons).
t. e. Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities. In these contexts, the capital letters and the small letters represent distinct and unrelated entities.
Time constant. In physics and engineering, the time constant, usually denoted by the Greek letter τ (tau), is the parameter characterizing the response to a step input of a first-order, linear time-invariant (LTI) system. [1][note 1] The time constant is the main characteristic unit of a first-order LTI system. It gives speed of the response.
The staurogram is encoded by Unicode in the Coptic block, at U+2CE8 ⳨ COPTIC SYMBOL TAU RO, and as of Unicode 7.0 (2014) also in the Ancient Symbols block, at U+101A0 𐆠 GREEK SYMBOL TAU RHO. The Coptic block has a ligature of the full word σταυρός, where the τρ is represented by the staurogram, and two lunate sigmas are attached ...
The symbol ϵ (U+03F5) is designated specifically for the lunate form, used as a technical symbol. The symbol ϑ ("script theta") is a cursive form of theta (θ), frequent in handwriting, and used with a specialized meaning as a technical symbol. The symbol ϰ ("kappa symbol") is a cursive form of kappa (κ), used as a technical symbol.
A shearing force is applied to the top of the rectangle while the bottom is held in place. The resulting shear stress, τ, deforms the rectangle into a parallelogram. The area involved would be the top of the parallelogram. Shear stress (often denoted by τ, Greek: tau) is the component of stress coplanar with a material cross section.
v. t. e. Theta (UK: / ˈθiːtə /, US: / ˈθeɪtə /) uppercase Θ or ϴ; lowercase θ[note 1] or ϑ; Ancient Greek: θῆτα thē̂ta [tʰɛ̂ːta]; Modern: θήτα thī́ta [ˈθita]) is the eighth letter of the Greek alphabet, derived from the Phoenician letter Teth . In the system of Greek numerals, it has a value of 9.
