[A+B+C=0^(@)],[sin A+sin B+sin C]

If A+B+C=0^(@) then sin A +sin B+sin C=

If A+B+C=0^(@) then sin A+sin B+sin C=

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

In any triangle ABC,sin^(2)A-sin^(2)B+sin^(2)C is always equal to (A) 2sin A sin B cos C(B)2sin A cos B sin C(C)2sin A cos B cos C(D)2sin A sin B sin C

If cos A+cos B+cos C=0sin A+sin B+sin C=0 and A+B+C=180^(@), then the value of cos3A+cos3B+cos3C is

If A+B+C=0 , then prove that sin 2A + sin 2B+ sin 2C=-4sin A sin B sin C .

In Delta ABC, if (sin A+sin B+sin C) (sin A+ sin B- sin C)=3 sin A sin B , then

sin(B+C-A)+sin(C+A-B)+sin(A+B-C)=4sin A sin B sin C

a sin A-b sin B=c sin(A-B)

a sin A-b sin B=c sin(A-B)
