Find the MacLaurin series of f(x) = ((e^x) - cos (x)) / x

2. Relevant equations

e^x = (x^n)/n!

cos x = ((-1)^(n) (x^(2n))) / (2n)!

3. The attempt at a solution

I'm just working on the numerator now, but I can't figure out how to subtract the MacLaurin series listed above to begin the problem. I did find a previous thread in this forum for the same problem, but it talked about if n was odd the cox x series would equal 0 and this doesn't make any sense to me. Can anybody help getting me started?
