    ok I get that too but then they have either a +npi or +2npi after it?

    that means that every half cirlce the values of cotangent repeat themselves anew

    well if it's + (any number of) pi then I could choose from: 2pi/3+npi or 2pi/3+2npi I'm thinking it would be: 2pi/3+npi

    n 2pi misses half of them; n pi covers all of them
