We consider the number of triangles formed by the intersecting diagonals of a regular polygon. Basic geometry provides a slight overcount, which is corrected by applying a result of Poonen and Rubinstein [1]. The number of triangles is 1... SE Sommars,T Sommars - 《Journal of Integer Sequ...
Calculation of Kua Number is based on a simple formula. For the calculation of Feng shui kua, 2 factor are taken into consideration - year of birth and Gender. Follow these simple steps to calculate Kua Number. Add the last two digits of your year of birth. If the resulting number is ...
We consider the problem of minimising the number of edges that are contained\nin triangles, among $n$-vertex graphs with a given number of edges. We prove a\nconjecture of F\"uredi and Maleki that gives an exact formula for this minimum,\nfor sufficiently large $n$.Vytautas Gruslys...
The th square number is equal to the sum of the st and th triangular numbers, (4) (5) as can seen in the above diagram, in which the st triangular number is represented by the white triangles, the th triangular number is represented by the black triangles, and the total number ...
