If sin A = sin B and cos A = cos B, A > B, then
  • a)
    sin (1/2) (A – (B) = 0
  • b)
    sin (1/2) (A + (B) = 0
  • c)
    cos (1/2) (A – (B) = 0
  • d)
    cos (1/2) (A + (B) = 0 
Correct answer is option 'A'. Can you explain this answer?

sin A = sin B ⇒ sin A - sim B = 0
...........(1)
and cos A = cos B ⇒ cos B - cos A = 0
    ..........(2)
Equations (1) and (2) are simultaneously true if sin (1/2) (A – (B) = 0,
while the other factors sin (1/2) (A+ (B) and cos (1/2) (A + (B) cannot both be zero simultaneously.
