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 surface), whose location satisfies or is determined by one or more specified conditions.
Geometrically, one studies the Euclidean plane (two dimensions) and Euclidean space. As taught in school books, analytic geometry can be explained more simply: it is concerned with defining and representing geometric shapes in a numerical way and extracting numerical information from shapes' numerical definitions and representations.

The CSE broadly covered GCSE grades C–G or 4–1 and the O-Level covered grades A*–C or 9–4, but the two were independent qualifications, with different grading systems. The separate qualifications were criticised for disadvantaging the bottom 42% of O-Level entrants, who failed to receive a qualification, and the highest-achieving CSE ...
Murderous Maths is a series of British educational books by author Kjartan Poskitt.Most of the books in the series are illustrated by illustrator Philip Reeve, with the exception of "The Secret Life of Codes", which is illustrated by Ian Baker, "Awesome Arithmetricks" illustrated by Daniel Postgate and Rob Davis, and "The Murderous Maths of Everything", also illustrated by Rob Davis.
[4] [5] [6] However, Mumford (1969) constructed an example of an abelian variety where Hdg 2 (X) is not generated by products of divisor classes. Weil (1977) generalized this example by showing that whenever the variety has complex multiplication by an imaginary quadratic field , then Hdg 2 ( X ) is not generated by products of divisor classes.
A spacetime diagram is a graphical illustration of locations in space at various times, especially in the special theory of relativity.Spacetime diagrams can show the geometry underlying phenomena like time dilation and length contraction without mathematical equations.
Chromosome 6 spans nearly 171 million base pairs (the building material of DNA) and represents between 5.5 and 6% of the total DNA in cells. It contains the major histocompatibility complex , which contains over 100 genes related to the immune response , and plays a vital role in organ transplantation .
