Pascal's Pyramid generator

Use this page to generate expansions of any trinomial, or confuse your friends. For (a+b+c)ⁿ simply generate a n^th order pascals triangle and put each term (e.g. a) in its own corner of the triangle, raise it to the power of n, then move one out step and reduce the exponent by one. By the time you get to the other side of the triangle the exponent should be 0. Its just like binomial expansion with an added dimention. If you want to expand something with more than 3 terms, I reccomend looking at Pascal's Simplex.
