2sin theeta-1=0
2sin theeta=1
sin theeta=1/2
theeta=sin 30°,sin 150°
only 2 solutions r possible

but the and is given infinite how it
It’s actually infinite because sin theta = 1/2 has infinite solutions starting from 30,150,390,510,750,870,1110,1230 and so on
The solutions will be in the form of 360x+30, 360x+150 where x belongs to whole numbers
cosx=cosy then x+y=___
