"In triangle ABC " "c(sin^(2)A+sin^(2)B)=sin C(a sin A+b sin B)

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

If A, B , C are angles in a triangle, then the sin ^(2)A+sin ^(2)B - sin ^(2) C =2 sin A sin B cos C

If A,B, C are angles in a triangle, then prove that: sin^(2) A + sin^(2) B - sin^(2) C =2 sin A sin B cos C

If quad A+B-C=180^(@) and sin^(2)A+sin^(2)B-sin^(2)C=K sin A sin B cos C, then the value of K is

If A+B+C=(pi)/(2) , then prove that sin ^(2) A+ sin ^(2) B + sin ^(2) C=1-2 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
