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...
(3) On page 136 of the workbook, we developed a formula for the shortest distance from a point to a plane. To briefly recap, suppose P = (21,41, 21) is a point with corresponding position vector p, and II is a plane with normal n = (a, b, c) given by ax + by + cz = d. Then the shortest distance from P to the plane is given by p-q|l, where Q is the point (with corresponding position vector...

Prove that lim inf,,0 In and lim inf, Yn are both in E. Hint: Use the sequential characterization of the closure, i.e., Proposition 3.2 from class. Problem 6. (3 pts) As usual let Q denote the set of all rational numbers. Prove that R....
Problem 4. Let n E N. We consider the vector space R” (a) Prove that for all X, Y CR”, if X IY then Span(X) 1 Span(Y). (b) Let X and Y be linearly independent subsets of R”. Prove that if X IY, then X UY is linearly independent. (C) Prove that every maximally pairwise orthogonal set of vectors in R” has n + 1 elements. Definition: Let V be a vector space and let U and W be subspaces...

(b) (10 points) (ryz) ds, where C is the line segment from the point (2, 1,0) to the point (4,3,6) (c) (10 points) F.dr,where F is the vector field F(x, y) = yi - rj and C is the curve given by r(t) t2i+...
state any definitions or theorems used Question 2. In this problem we'll prove that if a<b<c and f is integrable on [a, cl ther it's also integrable on [a,b] and [b, c'. Our approach will be to show that for all ε > 0 there are partitions Q1 and Q2 of [a, b) and [b, c] respectively with Thus, let ε > 0 be given. By our fundamental lemma there exists a partition P of [a, c) such that U...
Hello, can you please help me understand this problem? Thank you! 3. Let V be finite dimensional vector space. T is a linear transformation from V into W and E is a subspace of V and F is a subspace of W. Define T-(F) = {u € V|T(u) € F} and T(E) = {WE Ww= T(u) for someu e E}. (a) Prove that T-(F) is a subspace of V and dim(T-(F)) = dim(Ker(T)) + dim(F n Im(T)) (b) Prove that...
Please answer the parts 6 and 7. Thank you. 2. In this problem, we will prove the following result: If G is a group of order 35, then G is isomorphic to Zg We will proceed by contradiction, so throughout the following questions, assume that G is a group of order 35 that is not cyclic. Most of these questions can he solved independently I. Show that every element of G except the identity has order 5 or 7. Let...
Please answer the questions with clear handwriting. Thank you so much To prove that N(A) = C(AT)- we will be showing that a vector from either set is also in the other. 1. Prove Claim 1: If Xe N(A) then it is perpendicular to C(A) Outline: Let x be a vector in N(A), and consider the system of equations formed by Ax = 0. This will show that x is orthogonal to each row of A. Finally, show that x...
