In geometry, a prism is a polyhedron comprising an n-sided polygon base, a second base which is a translated copy (rigidly moved without rotation) of the first, and n other faces, necessarily all parallelograms, joining corresponding sides of the two bases.
The Siku Quanshu Zongmu Tiyao, or the Annotated Bibliography of the Four Treasuries, [1] is an annotated catalog of the thousands of works that were considered for inclusion in the Siku Quanshu (Complete Library of the Four Treasuries). Work for the 200-chapter catalog began in 1773 and was completed in 1798. [2]
The octant of a sphere is a spherical triangle with three right angles.. Spherical trigonometry is the branch of spherical geometry that deals with the metrical relationships between the sides and angles of spherical triangles, traditionally expressed using trigonometric functions.
Beyond the triangular bipyramid as its dual polyhedron, many other polyhedrons are related to the triangular prism. A Johnson solid is a convex polyhedron with regular faces, and this definition is sometimes omitted uniform polyhedrons such as Archimedean solids, Catalan solids, prisms and antiprisms. [12]
Shoelace scheme for determining the area of a polygon with point coordinates (,),..., (,). The shoelace formula, also known as Gauss's area formula and the surveyor's formula, [1] is a mathematical algorithm to determine the area of a simple polygon whose vertices are described by their Cartesian coordinates in the plane.

Siku (also spelled Siqu) (Aymara siku or siqu a kind of flute, also spelled Sekho, Seko) [2] or Siq'u (Quechua for slidable rope; perforated) [3] are the names of a ...
In probability theory and statistics, the Poisson distribution (/ ˈ p w ɑː s ɒ n /) is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time if these events occur with a known constant mean rate and independently of the time since the last event.

Citric acid is an organic compound with the formula C 6 H 8 O 7. [10] It is a colorless weak organic acid. [10] It occurs naturally in citrus fruits.In biochemistry, it is an intermediate in the citric acid cycle, which occurs in the metabolism of all aerobic organisms.
