The binomial theorem works in the same way if x or y is a constant instead of a variable. E is equal to : 42 43. makes sense for any n. The Binomial Series is the expansion (1+x)n = 1+nx+ n(n−1) 2! First, we deﬁne the binomial coeﬃcients n k =! using the convention that 0! E is equal to : 42 43. Using the binomial theorem is all the more important as the power increases, but even for the third power it is better to write (x+ y)3 = x3 +3x2y + 3xy2+y3 (∗∗) than to try to expand (x+y)(x+ y)(x+y).
