ParseError: syntax error, unexpected 'fn' (T_STRING), expecting :: (T_PAAMAYIM_NEKUDOTAYIM)
More info is available in the error log.

Polinômios trigonométricos: Toda função escrita como: $$ f(x) = a_0 + \sum_{n=1}^{m} a_n cos(nx) + b_n sin(nx) $$ onde $a_i, b_i$ são números complexos.

Lembrando que $$ cos(x) = \frac{1}{2}(e^{inx} + e^{-inx}) , \, sin(x) = \frac{1}{2i} (e^{inx} - e^{-inx})$$
