What are random variables?
Let f be analytic on a domain D. Prove that if f(z(0))=0 and if f is not identically zero, then z(0) is a zero of f of some finite order m.
Let f be analytic on a domain D. Prove that if f is not identically zero, then the zeros of f in D are isolated. (That is, prove that if f is not identically zero and if z(0) is a point in D with f(z(0))=0, then there exists e>0 such that f(z)=/0 for all z in the region 0<|z-z(0)|<e.) e, epsilon. =/, does not equal.

Can anybody explain and summarize the detail of John Nash's paper please? It is in the attachment file.
The Chinese Remainder Theorem (CRT) applies when the moduli ni in the system of equations x≡ a1 (mod n1) ... x≡ ar (mod nr) are pairwise relatively prime. When they are not, solutions x may or may not exist. However, the related homogeneous system (2'), in which all ai=0, always has a solution, namely the trivial
Respond/pick up the credit if you absolutely know the solution is correct. If you can make an improvement on the solution in correctness, clarity, presentation, or if a proof can be more elegant, than please rewrite the entire solution.
If the solution to this nonnegative integer question is correct, then you may respond that it is. If the solution needs ANY kind of improvement, in presentation, in clarity, in correctness, if a proof can be more elegant, then please rewrite the entire solution. See the attached file.
Suppose that f: C->C and that f is analytic at a point z0 element of C. Prove that there exists a real number r>0 such that, the nth derivative of z0=[n!/(2 pi r^n)]x[int(e^(-niy)f(z0+re^(iy)) from 0 to 2pi with respect to y for all n element of Natural numbers.
A Theorem states: Convex Sets are closed under convex combinations. That is, if C is a convex set, and if x1,x2,...,xm belongs to C then for all non-negative real numbers %1,%2,...,%m are non-negative real numbers such that $1+$2+....+$m=1, we have $1x1 + $2x2 + ... + $mxm belonging to C. Furthermore, I want to prove that i
Let a be an integer. Prove that 2a + 1 and a^2+ 1 are relatively prime. ( relative primes are numbers that their largest common divisor is 1). ONLY RESPOND IF THERE IS A a. mistake b. something is unclear c. proof is correct, but solved incorrectly (does not follow instructions) Exm. Instruction says proof by inducti
Take an in-depth look into this proof. Obviously it is wrong. Where is it wrong and why? This is obviously wrong. Where and why? Detailed explanation is needed of where and why it is wrong with all examples. Thanks Let a = b. Multiply both sides by a (OK because we don't violate the equal sign). We get a² = ab. Subtrac
At the start of the year, a company wants to invest excess cash in one-month, three-month and six-month Certificates of Deposit (CD's). (Purchase price and yields for the different CD's appear in the table below). The company is somewhat conservative, however, and wants to make sure that it has a safety margin of cash-on-hand e
I need assistance with following problem along with steps to arrive at the solution/answer. Three envelopes are addressed for 3 secret letters written in invisible ink. A secretary randomly places each of the letters in an envelope and mails them. What is the probability that at least 1 person receives the correct letter?

Let Pn be the product of the first n odd numbers. For example P_3 = 1 x 3 x 5 = 15. Prove that for positive integers n, P_n = (2n)!/(2^n)(n!) Your proof will be graded for style, clarity and completion.
Let S = {1,2,3,4,5,6,7,8}. Determine: (a) The number of subsets of S (b) The number of subsets of S with at most four elements (c) The number of ordered lists with elements chosen form S (with possible repetitions) (d) The number of ordered lists with nine elements chosen form S with no repetitions (e) The number
We can define sorted lists of integers as follows: Basis - A list consisting of a single integer is sorted. Induction - If L is a sorted list in which the last element is a and if b >= a, then L followed by b is a sorted list. Prove that this recursive definition of "sorted list" is equivalent to our original, nonrecurs
If no two strings in a code differ in fewer than three positions, the we can actually correct a single error, by finding the unique string in the code that differs from the received string in only one position. It turns out that there is a code of 7-bit strings that corrects single errors and contains 16 strings. Find such a cod
Please see the attached file for the full problem description. The double bracket notation is pronounced " n multichoose k". The doubled parentheses remind us that we may include elements more than once.
