I am reposting this probelm. Previous description was not enough. I thought this is high school math problem. However, it seems that this is beyound high...
As I understand, a cardioid is an epicycloid with one cusp. I have a few questions about this curve and an inverted cycloid with with arc length equal to the...
What are X, Y and Z?? They are not shown in your drawing. Tarcisio ________________ m I am reposting this probelm. Previous description was not enough. I...
X,Y,Z are the parameters in the generalization notation used. Using more familiar notation I provide the followingsolutions for GD and DF. Given: AB, CD=DE,...
Consider a set of 2*n consecutive integers. Divide this set in two arbitrary subsets A and B of n integers each. Now, order the integers in A from smallest to...
Sorry for my last post I thought that i was a multiplier if not I do get 16! Not arbitary but a sure fire method to solve is to divide the set 1-2n such that...
... I've not heard of the terminology "factor rate". If you mean what factor to multiply the original principle by to arrive at its future value (assuming...
Hi slim the due, i'm sorry. what i mean is factor rate on a monthly basis using 9% for a 20-year term. E.g. Principal - P2,408,000.00 Term - monthly over 20...
B should be sorted largest to smallest - A = {1,3} B = {4,2} ... From: slim_the_dude <TimKelleyGroups@...> To: mathforfun@yahoogroups.com Sent: Tuesday,...
Mr. ramsey2879@...: The first part of your argument is o.k..But how could I demonstrate "that exchanging any integer between A and B will not change the sum ? ...
hi. how do i show that a family of intervals is covering a certain set, i.e., how do i show that every point in a set is in at least one of the intervals of...
Hi again, Actually rule can be generalized and this solution can be used to prove that for any 2n integers the sums of the difference of A and B a constant...
Hi Chess Player, i got this question from my calculus class. I could actually visualize it, but then, i don't know how to show it in a mathematically elegant...
Yes, you are correct, but what was your reason? I think this is the most obvious argument: In a finite subfamily of F, 'a' can only take on a finite...
Yet more Theorems: For a 2n term arithmetic progression with term difference k, the sum of differences using this rule is kn^2. For a geometric progression...
I've been working on this problem for a very long time and I still haven't got anywhere and was wondering if someone could help. Over a decade ago, I was...
ok. But now, how do i show that every x in 0<x<1 is covered by 3a/(3+a)<x<3a/(3-a), where 0<a<1? surely, I can't use the greatest integer (or the floor())...
... not sure what you are asking. Do you want to know whether [ (1+x)^2 + y^2 ]^n/2 + [ (1-x)^2 + y^2 ]^n/2 = 2^n has any rational solutions? ... a ... ...
Hi, the following puzzle is simple to solve but only a few people have solved it till now. 3 from UK, 12 from Russia, 10 from US, 17 from India, 5 from Canada,...
