    en.wikipedia.org/wiki/Golden_ratio

    The golden ratio is also an algebraic number and even an algebraic integer. It has minimal polynomial. This quadratic polynomial has two roots, and. The golden ratio is also closely related to the polynomial. which has roots and As the root of a quadratic polynomial, the golden ratio is a constructible number.

    The fraction of the triangle's area that is filled by the square is no more than 1/2. Squaring the circle In 1882, the task was proven to be impossible as a consequence of the Lindemann–Weierstrass theorem , which proves that pi ( π ) is a transcendental number rather than an algebraic irrational number ; that is, it is not the root of any ...

    Glossary of mathematical symbols. A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various ...

  6. Locus (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Locus_(mathematics)

    Locus (mathematics) Set of points that satisfy some specified conditions. Each curve in this example is a locus defined as the conchoid of the point P and the line l. In this example, P is 8 cm from l. In geometry, a locus (plural: loci) (Latin word for "place", "location") is a set of all points (commonly, a line, a line segment, a curve or a ...

  7. Unit fraction - Wikipedia

    en.wikipedia.org/wiki/Unit_fraction

    In geometry, unit fractions can be used to characterize the curvature of triangle groups and the tangencies of Ford circles. Unit fractions are commonly used in fair division , and this familiar application is used in mathematics education as an early step toward the understanding of other fractions.

  8. Undefined (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Undefined_(mathematics)

    Undefined (mathematics) In mathematics, the term undefined is often used to refer to an expression which is not assigned an interpretation or a value (such as an indeterminate form, which has the possibility of assuming different values). [1] The term can take on several different meanings depending on the context. For example:

  9. Prism (geometry) - Wikipedia

    en.wikipedia.org/wiki/Prism_(geometry)

    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. All cross-sections parallel to the bases are translations of the bases.
