$sin17^\circ \cdot cos540^\circ \cdot tg\, 3660^\circ =\\\\=sin17^\circ \cdot cos(360^\circ+180^\circ)\cdot tg(10\cdot 360^\circ +60^\circ )=\\\\=sin17^\circ \cdot cos180^\circ \cdot tg\, 60^\circ =\\\\=sin17^\circ \cdot (-1)\cdot \sqrt3=-\sqrt3\, sin17^\circ \approx -0,29237\cdot 1,73205=-0,50640$
