>Hi All, >Who could help me and give the formule of the following: >(a+b)2 = 1a2 + 2ab + 1b2 >What is the formule of (a+b)n ??? >n is a variable number. >Thanx!!! >Yiorgos Wisse >Gerard.Wisse at nlehvfm1.origin.nl Try using the buillt-in function Binomial. E.G., n=4; Table[Binomial[n,j],{j,0,n}] gives {1,4,6,4,1} Or you may wish to use Expand Expand[(a+b)^2] gives a^2 + 2 a b + b^2 Hope this is what you were looking for. John C. Erb
