## Euclidean distance

Length of a line segment between the two points. The distance between any two points on the real line is the absolute value of the numerical difference of their coordinates.

## Magnitude (mathematics)

Property which determines whether the object is larger or smaller than other objects of the same kind. The absolute value (or modulus) of z may be thought of as the distance of P from the origin of that space.

## Holomorphic function

## Determinant

Scalar value that is a function of the entries of a square matrix. As pointed out above, the absolute value of the determinant of real vectors is equal to the volume of the parallelepiped spanned by those vectors.

## Even and odd functions

Even function if n is an even integer, and it is an odd function if n is an odd integer. If a function is odd, the absolute value of that function is an even function.
