MAT 4830Numerical Analysis Binomial Coefficients and Combinatorial Identities http://myhome.spu.edu/lauw
Goals • Binomial Theorem • Binomial Coefficients • Combinatorial Identities • Review shifting indices • Review Induction
Take Home Exam • Need Binomial Coefficients for the second problem. • Need Binomial Theorem for a few parts of the second problem.
Example 1 Find the coefficient of in the expansion of .
Index Shifting • Sigma representation of a summation is not unique
Index Shifting Rules increase the i in the summation by 1 decrease the index by 1
