Maximum of Rational Function
Hi, I am working with a rational function where both the numerator and denominator are quadratic polynomials, P(x) = q(x)/r(x) where q(x) = x^2 + b*x + c, and q(x) > 0 for all x in R r(x) = 1 + x^2 I can show treat the problem as a simple unconstrained optimization problem and find that the stationary... 20 May 2010 23:46

Euler's Rotation Theorem Proof
May I ask if someone can point me to a GEOMETRIC proof of Euler's Rotation Theorem? I do NOT mean the one using algebra - I really mean the one like in wiki. The problem with the wiki one is that, well, I do not understand it. There is a missing symbol "O" and I do not "see" the two angle symmetry planes. ... 20 May 2010 20:31

AffineSymmetricGroup
Let \tilde{S_n} be affine symmetric group. Elements x \in \tilde{S_n} are bijections from Z to itself satisfying: 1. x(i+n)=x(i)+n for all i \in Z. 2. \sum_{i=1}^n x(i)=(n+2)C2, where nCr denotes "n choose r". If the notation is not straightfoward, plz check it directly at source: http://www.math.ucdavis.edu/... 21 May 2010 07:19

ask a Q for help!
hi,friend: an equation (about r,k. m is a constant number): 2m^2+3m+1=2rm+k,here m,r,k are all positive integers.i test (m,r,k) many times,and find that r,k have the only one solution: r=k=m+1. but i cannt prove my guess.who can help me? thanks ... 24 May 2010 03:41
