- Let A =[ 4 -1 2 , -1 8 3 ,1 -2 5 ] b=[1 ,-2,3] and initial vector x 0=[0,0,0,0] perform two itearation of the gauss seidel methodarrow_forwardShow that the system x' =Ax has constant solutions otherthan x(t)= 0 if and only if there exists a (constant) vectorx ≠ 0 with Ax = 0. (It is shown in linear algebra that sucha vector x exists exactly when det(A) = 0.)arrow_forwardFind the maximum and minimum values, and a vector where each occurs, of the quadratic form subject to the constraint.z = 6x1x2; ||x||2 = 1arrow_forward
- (a) Show that the vector functions are linearly independent on the real line. (b) Why does it follow from Theorem 2 that there is no continuous matrixP(t) such that x1 and x2 are both solutions of x' = P(t)x?arrow_forwardIf A is invertible, i.e., for any given r.h.s. vector b, the system Ax = b has a solution. How can you compute the 3rd column of A^−1(what r.h.s. b would youchoose)?arrow_forwardSuppose A is a 2x2 invertible Martix. Is the following statement true or false? For each vector b, which is an element of R^2, there is one and only one vector x, which in an element of R^2, such that A*vector x=vector b.arrow_forward
