1) Let A be nxn matrix and Ax=b, if we need change A to Upper triangular matrix using Gaussian Elimination, how many additions/subtraction operations are involved? how many multiplication/division operations are involved?

2) Once we got the upper triangular matrix, now we need to apply back-substitution, how many additions/subtraction operations are involved? how many multiplication/division operations are involved?

Let Un×n be an upper triangular matrix of rank n. If any arithmetic operation takes 1µ second on a computing resource, compute the time taken to solve the system Ux = b, assuming it has a unique solution. What would be the time taken if Un×n is lower triangular

Let A be an m x n matrix. Prove that Ax = b has at least...

Let A be an m x n matrix. Prove that Ax = b has at least one solution for any b if and only if A has linearly independent rows. Let V be a vector space with dimension 3, and let V = span(u, v, w). Prove that u, v, w are linearly independent (in other words, you are being asked to show that u, v, w form a basis for V)

1. Let ??(F), ??(F) and ??(F) denote the spaces of strictly upper triangular, diagonal, and strictly lower triangular ?×? matrices over F, respectively. Show that ??(F) = ??(F)⊕??(F)⊕??(F). Compute the dimensions of these spaces and show they sum 2 up to ?. 2. Is the set {?3 +2?2,−?2 +3?+1,?3 −?2 +2?−1} in P3(R) linearly independent? Is it a basis?

Suppose the system AX = B is consistent and A is a 6x3 matrix. Suppose the maximum number of linearly independent rows in A is 3. Discuss: Is the solution of the system unique?

3. Let P be an nxn projection matrix (which means that it satisfies P2=P and PT=P)....

3. Let P be an nxn projection matrix (which means that it satisfies P2=P and PT=P). The goal of this problem is to show that P as a linear transformation is the orthogonal projection onto the range of P. (a) Show that if v is in the range of P, then Pv=v. (b) Show that if v is orthogonal to the range of P then Pv=0. (Hint: PPv lies in the range of P, hence is orthogonal to v. Study...
