Question

find sin x/2,cos x/2,tan x/2 if tan x=-4/3

Answer 1

since tan(x) is negative x is either in second quadrant or fourth quadrant...
If you assume x is in second quadrant then all sin x/2,cos x/2,tan x/2 are positive
If you assume x is in fourth quadrant cosx/2 and tanx/2 will be negative and sin x/2 will be positive

Answer 2

So, x lies in which quadrant???
