Please give me right answer with the details. Thanks! be an inner product on R". In this question you will show that there exists a n x n Let matric A such that (3.1) for all ,je R". Further you will show that A must be symmetric. (1) Suppose that such a matrix exists. That is suppose that there exists anxn matrix A = (a;^) for which (3.1 holds. Calculate (ē;, ë;) (2) Describe A in terms of (ēi,e;) 1...

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...

Orthogonal projections. In class we showed that if V is a finite-dimensional inner product space and U-V s a subspace, then U㊥ U↓-V, (U 1-U, and Pb is well-defined Inspecting the proofs, convince yourself that all that was needed was for U to be finite- dimensional. (In fact, your book does it this way). Then answer the following questions (a) Let V be an inner product space. Prove that for any u V. if u 0, we have proj, Pspan(v)...
For intro to analysis. Please answer true or false and give justification for your answer. Thanks! Mark the answers as ”TRUE” or "FALSE” on the front sheet. 1. Let f: Rd + R be continuous. Then the set {x e Rd : f(x) = 5} is closed. 2. Let f: Rd → R be continuous. Then the set {x € Rd: f(x) < 5} is open. 3. The rank of a p xq matrix is equal to min(p, q). 4....
Please help! Only answer questions 5-8! Definition 0.1. A sequence X = (xn) in R is said to converge to x E R, or x is said to be a limit of (xif for every e > 0 there exists a natural number Ke N such that for all n > K, the terms Tn satisfy x,n - x| < e. If a sequence has a limit, we say that the sequence is convergent; if it has no limit, we...
