Gon functions

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

Correct answer:

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

Step-by-step explanation:

sin (-33°) = -0.5446 < 0; -33 ° ... Q4; sin Q4 < 0
sin (889°) = 0.1908 > 0; 889 ° ... Q2; sin Q2 > 0
sin (-432°) = -0.9511 < 0; -432 ° ... Q4; sin Q4 < 0
cos (919°) = -0.9455 < 0; 919 ° ... Q3; cos Q3 < 0
cos (-16°) = 0.9613 > 0; -16 ° ... Q4; cos Q4 > 0
cos (-38°) = 0.788 > 0; -38 ° ... Q4; cos Q4 > 0
cos (222°) = -0.7431 < 0; 222 ° ... Q3; cos Q3 < 0
cos (546°) = -0.9945 < 0; 546 ° ... Q3; cos Q3 < 0
sin (-403°) = -0.682 < 0; -403 ° ... Q4; sin Q4 < 0
sin (-9°) = -0.1564 < 0; -9 ° ... Q4; sin Q4 < 0
