 Oct 12 awarded Yearling Oct 12 awarded Nice Question Apr 21 awarded Scholar Apr 21 accepted Generating-functions: is there a relationship between a generating function and the corresponding squared generating function Apr 21 comment Generating-functions: is there a relationship between a generating function and the corresponding squared generating function Know this is quite late, but thank you haha. Oct 10 awarded Autobiographer May 28 awarded Popular Question May 20 awarded Nice Answer Nov 28 awarded Commentator Nov 28 comment Singular value decomposition over finite fields? You can still use an unordered field, you just need that the inner-product maps to non-negative reals. Nov 28 answered Thorough Introduction to Singular Value Decomposition Nov 28 answered A random walk matrix has eigenvalue 1 with multiplicty 1 - why? Nov 20 comment Computing the maximum salary This wouldn't work for 2 people would it? Nov 20 comment Computing the maximum salary I like this question, hehe, simple but interesting. Nov 20 comment Infinite Ramsey theorem with infinitely many colours Kristal, I may be missing something, but when you say countably finite isn't that redundant, I mean all finite sets are countable by definition no? Nov 20 comment How to compute the rank of a matrix? haha I think its fine to have a misleading title as long as its all fun and games. Nov 19 answered Ways to Synthesize Topics in Linear Algebra Nov 11 comment Math History Question about the exponential function "entities must not be multiplied beyond necessity", thats all. Nov 9 comment Math History Question about the exponential function thanks for the answer, I suspect your reasoning is correct. Correct me if I am wrong but f continuous on isn't a sufficient condition. For example, take $f(x) = 1 \text{ for } x \in \mathbb{Q}$ and $f(x)=0 \text{ for } x \in \mathbb{R} \ setminus \mathbb{Q}$ then that method would imply f(x) is 1 everywhere, since f(x) is continuous on the rationals Nov 9 awarded Supporter
