Gon functions

Decide which of the numbers (values ​​of trigonometric functions) are positive and which are negative (or zero). Positive mark +1 and negative -1.

Result

sin (-33°):  -1
sin (889°):  1
sin (-432°):  -1
cos (919°):  -1
cos (-16°):  1
cos (-38°):  1
cos (222°):  -1
cos (546°):  -1
sin (-403°):  -1
sin (-9°):  -1

Solution:

sin (-33°) = -0.5446 < 0; -33 ° ... Q4; sin Q4 < 0
sin (889°) = 0.1908 > 0; 889 ° ... Q2; sin Q2 > 0
