Indeed, as we shall see, row and column operations preserve the property of the determinant being non-zero. More generally, there are simple rules that tell how a determinant when a row or column operation is applied. Theorem 1 (Multiplying a row by a scalar.) Let A be a square matrix. Let

If a family of vectors is linearly independent none of them can be written as a linear combination of finitely many other vectors in the collection. 3. If the determinant of a matrix is not equal to zero the vectors are linearly independent. Therefore, if the determinant of the matrix ...
WebThe rank of a matrix is the order of the highest ordered non-zero minor. Let us consider a non-zero matrix A. A real number 'r' is said to be the rank of the matrix A if it satisfies the following conditions:. every minor of order r + 1 is zero. There exist at least one minor of order 'r' that is non-zero. The rank of a matrix A is denoted by ρ (A). WebWhether the discriminant is greater than zero, equal to zero or less than zero can be used to determine if a quadratic equation has no real roots, real and equal roots or real and …
WebAnswer (1 of 4): One short way to look at it that avoids verbiage, is that: If the quadratic function is always more than zero, that means, when graphed on coordinate system, the function never intersects the X-axis. That means that the quadratic equation has no real solutions. So, the two thin...
