A diagonal matrix is a square matrix that has non-zero elements only in the diagonal that runs from the top left to the bottom right. A diagonal matrix is also a symmetrical matrix. More »

Matrix division means multiplying one matrix by the inverse of another matrix. Matrix A "divided by" matrix B is equivalent to matrix A multiplied by the inverse of matrix B. Mathematicians usually use the term "multiply... More »

A skew-symmetric matrix is a square matrix that is equal to the negative of its own transpose. Skew-symmetric matrices are also known as antisymmetric matrices. More »

The domain and range of parent functions can be determined by finding the values located farthest to the right, left, top and bottom of the graph. The domain of the graph includes the complete set of x-values while the r... More »

A symmetric matrix comes from linear algebra and is a square matrix that is symmetrical to the main diagonal, which is the connecting line running from the top left to the bottom right. The diagonal functions as a mirror... More »

To determine the number of entries in a matrix, count the number of elements inside the brackets. For example, a matrix having the elements -5, 2, 10, 4, 19 and -4 has six entries. More »

A triangular matrix is a special form of square matrix and can be either an upper triangular matrix or a lower triangular matrix. An upper triangular matrix occurs where all the entries below the main diagonal are zero, ... More »
