1 x x 2 x 3 ⋯ = 1 1 − x Alternatively the generating function is the product ( 1 x) ( 1 x 2) ( 1 x 4) ⋯ ( 1 x 2 n) ⋯ because this encapsulates the fact that each digit can Expand the left hand side Answer f' (x) = (2 x)/ (1x^2)^2 Guest #2 78 0 Firstly convert the fraction into a linear equation;Tan(x y) = (tan x tan y) / (1 tan x tan y) sin(2x) = 2 sin x cos x cos(2x) = cos ^2 (x) sin ^2 (x) = 2 cos ^2 (x) 1 = 1 2 sin ^2 (x) tan(2x) = 2 tan(x) / (1
