Sin(17п/3) = $sin(6 \pi - \frac{ \pi }{3} )=( \frac{- \sqrt{3} }{2} )$

cos(17п/4)= $cos(4 \pi + \pi /4)= \sqrt{2} /2$

cos(17п/3)= $cos(6 \pi - \frac{ \pi }{3} )=1/2$

tg(17п/6)= $tg(3 \pi - \pi /6)=- \frac{ \sqrt{3} }{3}$

sin 210 градусов = $sin( \pi + \pi /3)=-1/2$

cos 315 градусов = $cos(2 \pi - \pi /4)= \frac{ \sqrt{2} }{2}$

tg 480 градусов = $tg(3 \pi - \pi /3)=- \sqrt{3}$
