I have a web site that may be of interest to those in this forum. It is home to a sequence of computer programming contests, most of which are mathematical in nature.

The current contest is to determine the largest number of points that can be chosen from a cubic array of lattice points so that no 4 points are coplanar. First prize is any sculpture from Bathsheba Sculpture (http://bathsheba.com) worth up to $500. These sculptures, like the contests themselves, appeal to the mathematically inclined.

The competitions can be found at http://azspcs.com.

About this community

This community is specifically about the kind of mathematics needed to succeed in the various mathematics competitions around the world. The types of questions are often very different from standard school maths. This Mathematics Competitions community includes practice questions and learning materials. The overall aim is to improve your mathematical thinking skills. there is now a <spam trap>. As spammers are too lazy to read, it is normal to have it as the default top category. So please take some care when selecting an appropriate category - it must take all of 3 seconds to do so! Managed by GiftedMathematics.com

He says "no solution in positive intezers", means x,y,z to be taken from positive intezers.

(1) Why sin(30) = 1/2 ?
(2) i ^ 2 = -1 = rotation by 180°
(3) Transpose [A] = Rotation by 180.
(4) Diagonal of a matrix = Its axis of rotation.
(5) Why A x B = ABsin( )??
(6) Why Log(A x B) = Log(A) + Log(B) ???
(7) What is the purpose of curl and divergence??
(8) Purpose of differential equations.
For (6$)
