Thank you STEVE!!!!!

Suppose that Cos (theta) = 1/square root 2

sin(theta) =
tan (theta) =

If 3pi/2 less than equal to theta , 2pi then
sin(theta) =
tan (theta) =

I know the trig functions but I feel like I am missing something here. cos (theta) = adj/hyp sin(theta) = opp/ getting confused with the numbers I am getting..can you help me solve these?
