(eroare: eq.1/57513)$
S are n elemente, \forall n \in N , n \geq 2
S = \left\{(-1)^(n-1) + \tan \frac {k \pi}{n}|1 \leq k \leq n-1, k \in \N, k \neq \frac {n}{2} \right\}
S = \left \{(-1)^(n-1) + \cot \frac {k \pi}{n}| 1 \leq k \leq n-1, k \in \N \right \}
S = \left\{\cot \frac{k \pi}{n}| 1 \leq k \leq n-1, k \in \N \right\}
S \cap \R are cel mult doua elemente \forall n \in N, n \geq 2.
