WebHow many nonzero entries does the matrix representing the relation R on A = {1, 2, 3, ..., 500} consisting of the first 500 positive integers have if R = { (a, b) : a − b = 2}? (Show work! ) This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer WebUsually with matrices you want to get 1s along the diagonal, so the usual method is to make the upper left most entry 1 by dividing that row by whatever that upper left entry is. So say the first row is 3 7 5 1. you would divide the whole row by 3 and it would become 1 7/3 5/3 1/3. From there you use the first row to make the first column have ... simple smithing overhaul simplified
linear algebra - Suppose $A$ is a $4 \times 4$ matrix.
WebDec 7, 2024 · So a square matrix A of order n will not have more than n eigenvalues. So the eigenvalues of D are a, b, c, and d, i.e. the entries on the diagonal. So depending on the values you have on the diagonal, you may have one eigenvalue, two eigenvalues, or more. Anything is possible. Web1.
