Binomial theorem class 11 formula
WebA useful special case of the Binomial Theorem is (1 + x)n = n ∑ k = 0(n k)xk for any positive integer n, which is just the Taylor series for (1 + x)n. This formula can be extended to all real powers α: (1 + x)α = ∞ ∑ k = 0(α k)xk for any real number α, where (α k) = (α)(α − 1)(α − 2)⋯(α − (k − 1)) k! = α! k!(α − k)!. WebLet's see what is binomial theorem and why we study it. We know that (a + b) 2 = a 2 + b 2 + ab (a + b) 3 = a 3 + b 3 + 3a 2 b + 3ab 2 But what about big powers, like (a + b) 5 or (a + b) 9 or (a + b) 100 To find out these values, we use Binomial Theorem The topics in this chapter include What is Binomial Theorem Number of terms in Binomial Theorem
