I have coefficient of some expansion:
Workingexpansion = tau/n - (A tau^2)/(27 n^3) - (B tau^3)/(5832 n^5); CoefficientList[Workingexpansion, tau][]
I know, that, for example, when
i = 2, this coefficient is equal to
1/n, where n is integer. I'd like to check whether the coefficient is zero or not. I found some information here, but, unfortunately it didn't help me.
So this is what I did:
Assuming[ n ∈ Integers, TrueQ[Simplify[CoefficientList[Workingexpansion, tau][]] != 0]]
And I get
False. I don't know how to solve this problem.
