The determinant of a matrix of order three can be determined by expressing it in terms of second order determinants which is known as expansion of a determinant along a row (or a column).... MATH1025 AF. FW00F. Answers to Tutorial 4. Section 2.2. 2. If a matrix is triangular, its determinant is the product of the diagonal elements. Thus for part (a) the determinant is -30 and for part (b) it is -2.

**5.3 Determinants and Cramer’s Rule The University of Utah**

Find the determinant of the matrix with row vectors a+a, a+b, a+c. Solution. First, note that a+a = 2a, so that the ﬁrst row of the given matrix is obtained my multiplying the ﬁrst row of A by 2. We know that this has the eﬀect of multiplying the determinant of A by 2. Next, rows 2 and 3 of the given matrix are obtained by adding a scalar multiple of a row of A to another row of A, which... Under this baseless assumption, any matrix with the given eigenvalues would be enough to get the answer, so just choose the diagonal matrix that has the given eigenvalues and compute the answer. $\endgroup$ – DanielV Nov 6 '13 at 3:15

You get rid of the row, get rid of the column 4, 5, negative 2, 0. So now we just have to evaluate these 2 by 2 determinants. So the determinant right over here is going to be 5 times 0 minus 3 times 0. And all of that is going to be … how to find mass when given ph and volume Determinant definition is - an element that identifies or determines the nature of something or that fixes or conditions an outcome.
