@Payel: I think you are asking how many triangles you can form with integer sides and perimeter n. See http://oeis.org/A005044 for several formulas and for references. Dave On Dec 4, 2:41 am, payel roy smithpa...@gmail.com wrote: You have been given a number n. If you have to divide n into 3

the distance ap, bp and cp are the unknowns. we can get 3 simultaneous equations based on the condition that the permeters are same. ie, ab+ap= bc+pc ... and so on . 3 unknows and 3 equations = we can find the unknowns. once we find the distance ap and bp, finding the point 'p' is again solved by

Not really. The third equation is trivial and can be derived from other two. So in fact we have two equations and 3 unknowns. On 6/8/07, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: the distance ap, bp and cp are the unknowns. we can get 3 simultaneous equations based on the condition that
