Consider the following statements If `sinA=sinB,` then we have `sin 2A=sin 2B` always

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

Statement I: If sinA=sinB , cosA=cosB then A= 2np + B Statement II :If A+B+C=90^@ then sin2A+sin2B + sin2C = 4 sinA sinB sinC Which of the above statements is correct?

If sinA/sinB=sin(A-C)/sin(C-B) then

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

In sinA=sinB and cos A=cos B , then prove that sin(A-B)/(2)=0

In sinA=sinB and cos A=cos B , then prove that sin((A-B)/2)=0
