Question

помогите плиз!!!!!!!!!!!!!!!!​

Answer 1

Ответ:

$\pi = 180 \\ \frac{3\pi}{2} = \frac{3 \times 180}{2} = \frac{540}{2} = 270$

$\frac{3\pi}{4} = \frac{3 \times 180}{4} = \frac{540}{4} = 135$

$\frac{5\pi}{6} = \frac{5 \times 180}{6} = \frac{ 900}{6} = 150$

sin270°=-1

cos270°=0

tg270°=×

ctg270°=0

$sin135°= \frac{ \sqrt{2} }{2}$

$cos135°= - \frac{ \sqrt{2} }{2}$

tg135°=-1

ctg135°=-1

sin150°=1/2

$cos150°= - \frac{ \sqrt{3} }{2}$
