यदि `A+B+C=180^(@)` (अथार्त `pi`) तो सिद्ध करे कि
`(sin 2A+ sin 2B+ sin 2C)/(sinA+ sin B+ sin C)=8 "sin"(1)/(2)A."sin"(1)/(2)B. "sin" (1)/(2)C`

(sin2A + sin2B + sin2C) / (sin A + sin B + sin C) = 8sin ((A) / (2)) sin ((B) / (2)) sin ((C) / (2))

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

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

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)

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) .

If A+B+C= 180^(@) , " then " ( sin 2A- sin 2B- sin 2C)/(sin 2B- sin 2A - sin 2C)=

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

If A+B+C=pi , prove that: "sin" A+"sin" B-"sin" C=4 "sin"(A)/(2)"sin"(B)/(2)"cos"(C)/(2) .

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

If A+B+C=pi , prove that sin 2A+sin 2B+sin 2C=4 sinA sin B sinC.
