WebAnswer. For this question, we have been given a 2D vector and asked to perform a multiplication by the scalar quantity of 3. In order to do this, we can simply multiply both the π₯ and the π¦ component of the vector by the given scalar: 3 β π΄ = 3 ( β 1, β 8) = ( 3 ( β 1), 3 ( β 8)) = ( β 3, β 2 4). With some simplification ... WebBy the second property of determinants if we multiply one of those rows by a scalar, the matrixβs determinant, which is 0, is multiplied by that scalar, so that determinant is also 0. q.e.d. Theorem 2. The determinant of a matrix is not changed when a multiple of one row is added to another. Proof.

Web26 ian. 2012 Β· I think this misses the point. If you're dealing with a quaternion representing a rotation, then only a unit quaternion is valid. Scaling like this won't result in a unit quaternion for any scale other than 1.0. WebMultiplication of Two Determinants Define Determinants. A determinant can be β¦ WebVideo Transcript. If π΄ is a matrix of order two by two such that the determinant of π΄ is equal to three, find the determinant of three π΄. In this question, weβre given a matrix π΄, which is a square matrix. Itβs of order two by two. And weβre also told the determinant of π΄ is equal to β¦ education law may be defined as
