In triangleABC,sin((B+C)/2) =

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

In a Delta ABC,a^(2)sin2C+c^(2)sin2A is equal to

In triangleABC, sin((B-C)/(2))=

In triangleABC , if sin^(2)(A/2),sin^(2)(B/2),sin^(2)(C/2) be in H.P., then a , b , c will be in
