45. If sinA = sinB and cosA = cosB, then A equals:

If sinA = sinB and cosA = cosB then prove that, either A=B or they differ by multiples of four right angles.

If sinA = sinB and cosA=cosB, then which one of the following is correct ?

If sinA=sinB and cosA=cosB , then prove that sin((A-B)/2)=0

If sinA=sinB and cosA=cosB , then prove that sin. (A-B)/(2)=0 .

If sinA+sinB=a and cosA+cosB=b,then cos(A+B)

If sinA+sinB=a and cosA+cosB=b,then cos(A+B)

If sinA+sinB=l and cosA-cosA-cosB=m , then cos(A-B)=
