(sin2A+sin2B+sin2C)/(sin A+sin B+sin C)=

In DeltaABC,(sin 2A+ sin 2B+ sin 2C)/(sin A + sin B+ sin C)=

If A + B + C =pi , prove that : (sin 2A + sin 2B + sin 2C)/(sin A + sin B +sin C)= 8 sin frac (A)(2) sin frac (B)(2) sin frac (C)(2) .

Theorem 1:sin2A+sin2B+sin2C=4sin A sin B sin C

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

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

If A+B+C= pi and (sin 2 A + sin 2B + sin 2 C)/(sin A + sin B + sin C ) = lamda sin ((A)/(2)) sin ((B)/(2)) sin ((C )/(2)) , then the value of lamda must be

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=pi, the value of sin2A+sin2B+sin2C=k sin A sin B sin C then value of k is

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

If A+B+C= 180^(@) , then show that sin 2A+ sin 2B+ sin 2C =4 sin A sin B sin C .
