In DeltaABC , prove that: a) (sin2A + sin2B + sin2C)/(sinA+sinB+sinC) = 8sinA/2 sinB/2sinC/2

In DeltaABC , prove that: a) (sin2A + sin2B + sin2C)/(sinA+sinB+sinC) = 8sin(A/2) sin(B/2)sin(C/2)

If A+B+C=pi , prove that : (sin 2A+sin 2B + sin 2C)/(sinA+sinB+sinC) = 8 sin(A/2) sin(B/2) sin(C/2)

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?

(sin(A-C)+2sinA+sin(A+C))/(sin(B-C)+2sinB+sin(B+C)) is equal to
