Question

.

Answer 1

are you allowed to use a calculator?
if so, test each choice

Answer 2

Though normally, people memorize the sin, cos and tan of some special angles

what did you get for sin(2 pi) ?

Answer 3

that means your calculator is in "degree mode"
but the angles in your question are in radians.

You should change the calculator to radian mode
and then test the choices

Answer 4

or, change the choices from radians to degrees, then test them with the calculator

Answer 5

If you want to get good at these questions, you should memorize a few of these angles
0 deg = 0 rad
30 deg = pi/6 rad
45 deg= pi/4 rad
60 deg = pi/3 rad
90 deg = pi/2 rad
360 deg = 2 pi rad (and the same as 0 deg)

Answer 6

yes, sin(360º) = sin(0º) = 0
tan(360º) = tan(0º) = 0
