Week – 16 | Binomial Theorem – 3
1.1 Evaluating expressions by Differentiation Often, we would need to call up Calculus to compute Binomial Expressions and sums. We’ll represent as from here on. Let’s consider a small example: Ex -1: Show that Solution: If the positive integers appear as the product of Binomial coefficients, then that’s a hint that the problem may be… Continue reading
Week – 16 | Binomial Theorem – 2
1.1 Basics of the Binomial Theorem , where . This is what we call the Binomial Theorem, and holds for all reals . In the above theorem, if we put , we arrive at the following identity: . Combinatorially speaking, out of a set of elements, the total number of ways that a selection can be formed… Continue reading
