Question

дайте пожалуйста полный ответ ​

Answer 1

Объяснение:

1)

$\sin(3\pi) = 540 = 0$

$\cos(5\pi) = 900 = - 1$

$\cos(6\pi) = 1080= 1$

cos6Пи,sin3Пи,cos6Пи

2)

$\sin( \frac{\pi}{2} ) = 90 = 1$

$\cot( \frac{3\pi}{2} ) = 270 = 0$

$\cos(\pi) = 180 = - 1$

cosПи,сot3Pi/2,sinpi/2

3)

$\cos( \frac{15\pi}{2} ) = 1350 = 0$

$\cos(17\pi) = 3060 = - 1$

$\sin( \frac{33\pi}{2} ) = 2970 = 1$

cos17pi,cos15pi/2,sin33pi/2

4)

$\tan(21\pi) = 3780 = 0$

$\sin( \frac{43\pi}{2} ) = 3870 = - 1$

$\cos(100\pi) = 18000 = 1$
