- . Is it always true that T(0) = 0 where the zero vectors live in the appropriatespaces? Justifyarrow_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_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_forward
- Find a basis of solutions by the frobenius method. Xy'' + 2y' + xy = 0arrow_forwardProve that if y1 and y2 are linearly independent solutions to thehomogeneous, then the functions y3 = y1 + y2 and y4 = y1 - y2 are also linearly independent solutions.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_forward
- Suppose 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_forwardProve that the system of parabola y2= 4a(x+a) is self orthogonalarrow_forward
