A letter or symbol that stands for a specific number,

• Definite integral

The definite integral of the function ƒ over [a,b] is Lbaƒ(x) dx = limn: q ani=1 ƒ(xi) ¢x provided the limit of the Riemann sums exists

• Difference identity

An identity involving a trigonometric function of u - v

• Directed distance

See Polar coordinates.

• Inverse of a matrix

The inverse of a square matrix A, if it exists, is a matrix B, such that AB = BA = I , where I is an identity matrix.

• Multiplicative identity for matrices

See Identity matrix

• nth root of unity

A complex number v such that vn = 1

• Parallelogram representation of vector addition

Geometric representation of vector addition using the parallelogram determined by the position vectors.

• Proportional

See Power function
