Mr. X is glad to provide video presentations of hundreds of advanced algebra glossary terms. The advanced algebra glossary is part of a complete math glossary available free of charge on the website. All advanced algebra glossary terms are provided free of charge to all users.
Title Description
Deductive Logic Deductive Logic is employed before events have transpired, before the fact.
Degree, Polynomial The Degree of a polynomial is the order, or highest power (term) of the polynomial.
Determinant A Determinant is a number associated with a square matrix.
It may also be a cofactor, a number associated with a square array from a larger matrix.
Diagonal Matrix A square matrix with zero values everywhere except on the main diagonal (upper left to lower right) is termed a Diagonal Matrix.
Dimension, Matrix The Dimension of a matrix is its order, or size.
We label the order of a matrix by its number of rows then its number of columns.
A 4x3 matrix is read as "a four by three matrix" and has four rows and three columns.
Discontinuity When a function is literally not continuous because of a gap, a step, a hole, or any kind of "break" it is considered discontinuous.
Discrete Function When the inputs from the domain of the function are not smooth and continuous but rather incremental, the function is considered to be a Discrete Function.
