For example, the unit circle is defined by the implicit equation . In general, every implicit curve is defined by an equation of the form
for some function F of two variables. Hence ... |

https://en.wikipedia.org/wiki/Meusnier%27s%20theorem | In differential geometry, Meusnier's theorem states that all curves on a surface passing through a given point p and having the same tangent line at p also have the same normal curvature at p and their osculating circles form a sphere. The theorem was first announced by Jean Baptiste Meusnier in 1776, but not published... |
https://en.wikipedia.org/wiki/Chinese%20hypothesis | In number theory, the Chinese hypothesis is a disproven conjecture stating that an integer n is prime if and only if it satisfies the condition that is divisible by n—in other words, that an integer n is prime if and only if . It is true that if n is prime, then (this is a special case of Fermat's little theorem), ho... |

https://en.wikipedia.org/wiki/Vertex%20%28geometry%29 | In geometry, a vertex (: vertices or vertexes) is a point where two or more curves, lines, or edges meet or intersect. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedra are vertices.
Definition
Of an angle
The vertex of an angle is the poin... |

https://en.wikipedia.org/wiki/Dimension%20function | In mathematics, the notion of an (exact) dimension function (also known as a gauge function) is a tool in the study of fractals and other subsets of metric spaces. Dimension functions are a generalisation of the simple "diameter to the dimension" power law used in the construction of s-dimensional Hausdorff measure.
