Sender: "Howard E. Lutz" How do you find each successive numerical term in this equation y+dy=(x+dx)^{5} =x^{5}+5*x^{4}dx+10*x^{3}(dx)^{2}+10*x^^{2}(dx)^{3}+5*x(dx)^{4}+(dx)^{5} I would appreciate an explanation of the method to find the numeric coefficient in a binomial expansion Thanking you in advance Hi Howard,In the binomial expansion of (a + b)^{n} each term is a constant times a^{k}b^{nk} where the constant is n choose k. that is
The binomial coefficient n choose k, written is given by Penny
