The following exercise shows that the converse to Lagrange's theorem is false, i.e. even if d ||G|, there need not be a subgroup of G with order d. (a) Let n > 4 and consider the alternating group An. Suppose that NC An is a normal subgroup and that there is a 3-cycle (abc) E N. Prove that N = An. Hint: it is enough to show that N contains all 3-cycles. What is the conjugate of...

And Heres theorem 10.1
Prove that the relation VR of Theorem 10,1 is an equivalence relation. ① show that a group with at least two elements but with no proper nontrivite subgroups must be finite and of prime order. 10.1 Theorem Let H be a subgroup of G. Let the relation ~1 be defined on G by a~lb if and only if albe H. Let ~R be defined by a~rb if and only if ab- € H. Then ~1 and...
Theorem 16.1. Let p be a prime number. Suppose r is a Gaussian integer satisfying N(r) = p. Then r is irreducible in Z[i]. In particular, if a and b are integers such that a² +62 = p, then the Gaussian integers Ea – bi and £b£ai are irreducible. Exercise 16.1. Prove Theorem 16.1. (Hint: For the first part, suppose st is a factorization of r. You must show that this factorization is trivial. Apply the norm to obtain p=...

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...
Use MATLAB to prove the central limit theorem. To achieve this, you will need to generate N random variables (I.I.D. with the distribution of your choice) and show that the distribution of the sum approaches a Guassian distribution. Plot the distribution and matlab code. Hint: you may find the hist) function helpful.
Explain this Theorem as if you talking to a 5 year old
Theorem 22 For any pe2, p-* c,e,. defined by (6-57) where the numbers cr are c.-p.en The proof of this is not quite as trivial as it looks. If we start with p-(a1, a2, ), then (6-57) immediately gives a.-c" for all n, and all that remains is to show that (6-58) Cn e The only question lies in knowing what the right side means. As with series...
1. (a) State and prove the Mean-Value Theorem. You may use Rolle's Theorem provided you state it clearly (b) A fired point of a function g: (a, bR is a point cE (a, b) such that g(c)-c Suppose g (a, b is differentiable and g'(x)< 1 for all x E (a, b Prove that g cannot have more than one fixed point. <「 for (c) Prove, for all 0 < x < 2π, that sin(x) < x.
