-- Wrong limits do not commute
|
| |
An excercise, in mathematics, always consists of two parts: a question and an answer. Some teachers think that they are smart by asking wrong questions and nevertheless expect right answers to those questions. But, of course, the "right" answer to a wrong question is still wrong. Especially with limits, wrong questions are imposed upon students, in... more »

-- finding an element of order p
|
| |
...No. Instead take an element x of P\{identity}. It has order p^n for some natural number n. If n=1 - great. Otherwise the element x^(p^(n-1)) has order p since by definition p^n is the smallest natural number m such that x^m=1. H

roots to 4th, 5th, 6th & 7th degree polynomials [link] The best I can promise is all denominators are nonzero, and dimensional analysis passes. See if you can understand the concept. If it works, it can find the roots to any degree polynomial. If it doesn't, then at best it may give a rough... more »

Statistics question
|
| |
"How does one measure the variation (change/variability) in small groups with respect to a large group?" This is to make an opinion poll regarding a small business. We want to know what the impact of this variation (change/variability) is."

JSH: More with Quadratic Diophantine Theorem
|
| |
I introduced a nifty new theorem in another thread which has become bogged down with replies so here's a new thread where I can bring focus back to the theorem itself. Quadratic Diophantine Theorem: In the ring of integers, given the quadratic expression c_1*x^2 + c_2*xy + c_3*y^2 = c_4*z^2 + c_5*zx + c_6*zy... more »
