A triangular function (also known as a triangle function, hat function, or tent function) is a function whose graph takes the shape of a triangle. Often this is an isosceles triangle of height 1 and base 2 in which case it is referred to as the triangular function.
The Källén function, also known as triangle function, is a polynomial function in three variables, which appears in geometry and particle physics. In the latter field it is usually denoted by the symbol λ {\displaystyle \lambda } .
Melinoë (/ m ɪ ˈ l ɪ n oʊ iː /; Ancient Greek: Μηλινόη, romanized: Mēlinóē pronounced [mɛːlinóɛː]) is a chthonic goddess invoked in one of the Orphic Hymns (2nd or 3rd centuries AD?), and represented as a bringer of nightmares and madness.
A real-valued function f of three real variables a, b, c may have the following properties: Homogeneity: f(ta,tb,tc) = t n f(a,b,c) for some constant n and for all t > 0. Bisymmetry in the second and third variables: f(a,b,c) = f(a,c,b). If a non-zero f has both these properties it is called a triangle center function.
The Möller–Trumbore ray-triangle intersection algorithm, named after its inventors Tomas Möller and Ben Trumbore, is a fast method for calculating the intersection of a ray and a triangle in three dimensions without needing precomputation of the plane equation of the plane containing the triangle.

Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle' and μέτρον (métron) 'measure') [1] is a branch of mathematics concerned with relationships between angles and side lengths of triangles.
Take Pascal's triangle, which is a triangular array of numbers in which those at the ends of the rows are 1 and each of the other numbers is the sum of the nearest two numbers in the row just above it (the apex, 1, being at the top). The following is an APL one-liner function to visually depict Pascal's triangle:
Here is an implementation of the Romberg method (in the Python programming language): ... Args: f: The function to integrate. a: Lower limit of integration. b: ...
