If A+B+C=270^(@) then sin 2A+sin2B+sin2C=

If A+B+C=90^(@) then sin^(2)A+sin^(2)B+sin^(2)C=

Statement: If sin A =sin B, cos A=cos B then A=2n pi +B Statement :II If A+B+C=90^(@) then sin 2A+sin 2B+sin 2C=sin A sin B sin C Which of the above statement is correct?

If A+B+C=90^(@) then prove that sin2A+sin2B+sin2C=4cosAcosBcosC

If A+B+C=0^(@) then prove that sin2A+sin2B+sin2C=-4sin A sin B sin C

If A+B+C=180^(@) , then prove that sin2A+sin2B+sin2C=4 sin A sin B sin C .

If A+B+C=180^(@), then prove that sin2A+sin2B+sin2C=4sin A sin B sin C
