If sin a b 1 2
- If sin a b 1 2 and cos
- If sin a b c 1 2
- If sin a b )= 1 and sin ab )= 1 2
- If sin a b 1 cos a b 3 2
- If sin a 1 2 and cos b 1 2 then ab
- If sin a 1 2 and cos b 1 2 then the value of ab is
- If sin a 1 2 cos b 12 13
- If sin a b 1 and cos ab )= √ 3 2
- If sin a b 1 2 cos a b 1 2 0
- If sin a b 3 2 and sin 2b 1 2 then
- If sin a b 1 2 and cos a b 1 2 then
- If sin a minus b equal to 1 by 2
