Please answer with the details. Thanks! In this problem using induction you prove that every finitely generated vector space has a basis. In fact, every vector space has a basis, but the proof of that is beyond the scope of this course Before trying this question, make sure you read the induction notes on Quercus. Let V be a non-zero initely generated vector space (1) Let u, Vi, . . . , v,e V. Prove tfe Span何, . . ....

please help if you know Optimization with Quadratic Functions Could you please prove 89. Thank you so much ! Quadratic Functions A quadratic function is a mapping Q R R that is a scalar combination of single variables and pairs of variables. Thus, there are coefficients Cli,] and Ell, and a real number q, such that for X E IRn, we have The m atrix notation for C is suggestive. Indeed, C is n × n, and we take E...
explain the answer with clear handwriting please Questions: 1. [10 pts] There are two players A and B. The probability that A wins a game is 0.4, and the probability that B wins a game is 0.6. We randomly choose one player between A and B and let the chosen player play 10 independent identical games. An amount Xin dollars) is rewarded to each win, where X has a continuous uniform distribution over (0,60). Let X be the total amount...

An important fact we have proved is that the family (enr)nez is orthonormal in L (T,C) and complete, in the sense that the Fourier series of f converges to f in the L2-norm. In this exercise, we consider another family possessing these same properties. On [-1, 1], define dn Ln)-1) 0, 1,2, Then Lv is a polynomial of degree n which is called the n-th Legendre polynomial. (a) Show that if f is indefinitely differentiable on [-1,1], thern In particular,...
