• Augmented matrix

A matrix that represents a system of equations.

• Constant term

See Polynomial function

• Conversion factor

A ratio equal to 1, used for unit conversion

See Polar coordinates.

• Equation

A statement of equality between two expressions.

• Factoring (a polynomial)

Writing a polynomial as a product of two or more polynomial factors.

• Five-number summary

The minimum, first quartile, median, third quartile, and maximum of a data set.

• Law of cosines
