artesian coordinate system
An association between the points in a plane and ordered pairs of real numbers; or an association between the points in threedimensional space and ordered triples of real numbers

Characteristic polynomial of a square matrix A
det(xIn  A), where A is an n x n matrix

Degree
Unit of measurement (represented by the symbol ) for angles or arcs, equal to 1/360 of a complete revolution

Distance (on a number line)
The distance between real numbers a and b, or a  b

Equal matrices
Matrices that have the same order and equal corresponding elements.

Equilibrium price
See Equilibrium point.

Equivalent arrows
Arrows that have the same magnitude and direction.

Linear correlation
A scatter plot with points clustered along a line. Correlation is positive if the slope is positive and negative if the slope is negative

Logarithmic regression
