In trigonometry , the sinus totus (Latin for "total sine") was historically the radius of the base circle used to construct a sine table; that is, the maximum possible value of the sine.
Letting the notation Sin θ {\displaystyle \operatorname {Sin} \theta } stand for the historical sine, and sin θ {\displaystyle \... | https://en.wikipedia.org/wiki/Sinus_totus |
The versine or versed sine is a trigonometric function found in some of the earliest ( Sanskrit Aryabhatia , [ 1 ] Section I) trigonometric tables . The versine of an angle is 1 minus its cosine .
There are several related functions, most notably the coversine and haversine . The latter, half a versine, is of particul... | https://en.wikipedia.org/wiki/Sinus_versus |

A siphon (from Ancient Greek σίφων ( síphōn ) ' pipe, tube ' ; also spelled syphon ) is any of a wide variety of devices that involve the flow of liquids through tubes. In a narrower sense, the word refers particularly to a tube in an inverted "U" shape, which causes a liquid to flow upward, above the surface of a rese... | https://en.wikipedia.org/wiki/Siphon |
In computational complexity theory , the Sipser–Lautemann theorem or Sipser–Gács–Lautemann theorem states that bounded-error probabilistic polynomial (BPP) time is contained in the polynomial time hierarchy , and more specifically Σ 2 ∩ Π 2 .
In 1983, Michael Sipser showed that BPP is contained in the polynomial time ... | https://en.wikipedia.org/wiki/Sipser–Lautemann_theorem |
