How do you represent a system of linear equations in matrix form?

Back

A system of linear equations can be represented in matrix form as Ax = B, where A is the coefficient matrix, x is the variable matrix, and B is the constant matrix.

What is the significance of the determinant in matrix operations?

Back

The determinant is a scalar value that can indicate whether a matrix is invertible; if the determinant is zero, the matrix is not invertible.

Front

What is a linear combination of vectors?

Back

A linear combination of vectors is an expression formed by multiplying each vector by a scalar and adding the results together.

Front

What is the difference between a row matrix and a column matrix?

Back

A row matrix has a single row and multiple columns, while a column matrix has a single column and multiple rows.

Front

What is the rank of a matrix?

Back

The rank of a matrix is the dimension of the vector space generated by its rows or columns, indicating the maximum number of linearly independent row or column vectors.
