Diophantine equation
-- 06:23, 20 December 2005 (UTC) -- Q12: Consider a linear [ [Diophantine equation]] $$a\cdot x + b\cdot y = c. $$

How many solution pairs $$ \langle x,y\rangle $$ for $$ 0 \le x \le M $$ does the equation have?

Hint: Use [ [Pick's theorem]].

Internal diagonals
-- 12:31, 7 December 2005 (UTC) -- An addition to [ [Talk:Diagonal]]

We know that the number of [ [diagonal]]s in an [ [polygon|n-gon]] is


 * $$d= \frac{n^2-3n}{2}.\, $$

About internal diagonals one can ask:
 * What is the maximal number of them?
 * What is the minimal number of them?

The first question is easy. The number d above is the maximal number of internal diagonals and happens for [ [convex]] [ [polygon]]s.

But can you answer the second question?

There is an easy construction of an n-gon with (n-3) internal diagonals. Is this the minimum?

School children questions
-- 07:14, 15 January 2006 (UTC) -- An addition to school children questions based on [ [Polygon#Properties]].

Qn = A question for n-graders.

" so 2n-4 for [ [shape]].

In the case of a line of symmetry the latter reduces to n-2."

Q09: Prove this statement.

Q07: Are all convex equilateral and equiangular polygons cyclic?

PA, PAS (Parental Alienation, Parental Alienation Syndrome). (see: http://www.parentalalienation.com/pasdirectory.htm, http://www.falseallegations.com/pas-bw3.htm, or http://www.divorceinfo.com/pas.htm) not in DSM IV-TR (see: [ [DSM-IV]], or http://www.psychnet-uk.com/dsm_iv/dsm_iv_index.htm) but "discalculia" is in DSM IV (math learning disability!), see [ [Discalculia]].)

DSM IV-TR doesn't list ACOA-syndrome directly (see [ [Codependence]], http://www.recovery.org/acoa/acoa.html a http://www.adultchildren.org/), but lists "codependent personality disorder" (http://www.psychnet-uk.com/clinical_psychology/criteria_personality_codependent.htm), however, Parkinson's Disease is not listed there...
