- In mathematics, sine and
cosine are
trigonometric functions of an angle. The sine and
cosine of an
acute angle are
defined in the
context of a
right triangle:...
- analysis,
cosine similarity is a
measure of
similarity between two non-zero
vectors defined in an
inner product space.
Cosine similarity is the
cosine of the...
- trigonometry, the law of
cosines (also
known as the
cosine formula or
cosine rule)
relates the
lengths of the
sides of a
triangle to the
cosine of one of its angles...
-
trigonometric functions most
widely used in
modern mathematics are the sine, the
cosine, and the
tangent functions.
Their reciprocals are
respectively the cosecant...
- A
discrete cosine transform (DCT)
expresses a
finite sequence of data
points in
terms of a sum of
cosine functions oscillating at
different frequencies...
- In
spherical trigonometry, the law of
cosines (also
called the
cosine rule for sides) is a
theorem relating the
sides and
angles of
spherical triangles...
- In
analytic geometry, the
direction cosines (or
directional cosines) of a
vector are the
cosines of the
angles between the
vector and the
three positive...
- The raised-
cosine filter is a
filter frequently used for pulse-shaping in
digital modulation due to its
ability to
minimise intersymbol interference (ISI)...
-
functions are:
hyperbolic sine "sinh" (/ˈsɪŋ, ˈsɪntʃ, ˈʃaɪn/),
hyperbolic cosine "cosh" (/ˈkɒʃ, ˈkoʊʃ/), from
which are derived:
hyperbolic tangent "tanh"...
-
Madhava series is one of the
three Taylor series expansions for the sine,
