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 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.

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.
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 } .
The following pseudocode describes a basic implementation of the Bowyer-Watson algorithm. Its time complexity is ().Efficiency can be improved in a number of ways. For example, the triangle connectivity can be used to locate the triangles which contain the new point in their circumcircle, without having to check all of the triangles - by doing so we can decrease time complexity to ().
where γ m are the Stieltjes constants and δ m,0 represents the Kronecker delta function. Notice that this last identity immediately implies relations between the polylogarithm functions, the Stirling number exponential generating functions given above, and the Stirling-number-based power series for the generalized Nielsen polylogarithm functions.
The Steiner point S is located at the Fermat point of the triangle ABC. Solution for four points—there are two Steiner points, S 1 and S 2. In combinatorial mathematics, the Steiner tree problem, or minimum Steiner tree problem, named after Jakob Steiner, is an umbrella term for a class of problems in combinatorial optimization.
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: ...
