The above expansion holds because the derivative of e x with respect to x is also e x, and e 0 equals 1 This leaves the terms (x − 0) Since the cosine is an even function, the coefficients for all the odd powers x, x 3, x 5, x 7, have to be zero Second exampleUsing the above identity taking a = x − y, b = y − z and c = z − x, we have a b c = x − y y − z z − x = 0 then the equation (x − y) 3 (y − z) 3 (z − x) 3 can be factorised as follows How many terms in the expansion of (xyz)^100?
