Explanation & Answer
please ask if any question...
Q1: In your own words, explain how to form the rows of Pascal’s triangle.
n
Answer: In the expansion of ( x y ) , coefficients of the expansion can readily be calculated by
n
Pascal’s triangle. Coefficients of ( x y ) come from the n th row of Pascal's Triangle, in which
each term is the sum of the two terms just above it. We start to generate Pascal’s triangle by
writing down the number 1. Then we write a new row with the number...
