Explanation:
Given that,
sin 4530º = sin(50×90º+30º)
So if we divide 50 by 4 we get the remainder 2 then the angle is in third quadrant and in
third quadrant sine is negative and since the multiple of 90º is even so will be .
=-sin30º=-1/2, since sin30º=1/2
Final Answer:
Hence the correct option is (2).i.e -1/2
