WebThe Discriminant - Concept. The discriminant is the term underneath the square root in the quadratic formula and tells us the number of solutions to a quadratic equation. If the discriminant is positive, we know that we have 2 solutions. If it is negative, there are no solutions and if the discriminant is equal to zero, we have one solution. WebThe determinant of a skew-symmetric matrix having an order equal to an odd number is equal to zero. So, if we see any skew-symmetric matrix whose order is odd, then we can directly write its determinant equal to 0. Let's verify this property using a 3×3 matrix as follows: \(B = \left[\begin{array}{ccc} 0 & a & b \\-a & 0 & m \\-b & -m & 0

Indeed, the main motivation when learning all of this is often to check when a matrix is ‘zero-determinant’ or not. But what does such a matrix do in terms of linear transformations ... WebSolve the system of equations using Cramer’s Rule: { 3 x + y − 6 z = −3 2 x + 6 y + 3 z = 0 3 x + 2 y − 3 z = −6. Cramer’s rule does not work when the value of the D determinant is 0, as this would mean we would be dividing by 0. But when D = 0, the system is either inconsistent or dependent. how much is trump nft worth today
