Simple question about fourier representation
Hello mathematicians, Consider a function f_n(x) defined on [-pi,pi] that is represented with n frequency components: f_n(x)=sum_{k=1}^n a_k cos(kx) + b_k sin(kx) The set {a_k,b_k} for k=1,...n is given. The function f_n may have multiple peaks (I think at most 2n). By a peak I mean a point that is a local ... 3 Jul 2010 21:09

can we use the geometry template of finite-line vs. infinite-line to precision define finite-number vs. infinite-number? #626 Correcting Math
Let me get back to the more important math, rather than chasing down mistakes of logic in Euclid's IP proof. So we have the geometry side of mathematics with a precision definition of finite-line versus infinite-lines. Those definitions involve the fact that a finite-line is a line segment with two endpoints. ... 3 Jul 2010 03:42

Some mathematical truth
Einsteinian math can be used to define the speed of light limit in the universe. It is E=MC Squared and the Gamma factor but they are solved for C instead. Factoring this Einsteinian math reveals a new mathematical truth of the speed of light. Mitch Raemsch ... 8 Jul 2010 16:59
