void acb_sin_pi(acb_t r, const acb_t z, slong prec)source
void acb_cos_pi(acb_t r, const acb_t z, slong prec)source

void acb_cot_pi(acb_t r, const acb_t z, slong prec)source
void acb_csc_pi(acb_t y, const acb_t x, slong prec)source

Set the output to \sin(\pi z), \cos(\pi z), both, \tan(\pi z), \cot(\pi z), respectively \csc(\pi z), using arb_sin_cos_pi for the real part so that the results are accurate near the zeros.
