" 1.Show that "sum a(sin B-sin C)=0

In a /_ABC, show that sum a sin(B-C)=0

Show that suma sin(B-C) =0

If A, B, C are angles of triangle ABC and a, b, c are lengths of the sides opposite to A, B, C respectively, then show that : a (sin B - sin C)+ b (sin C- sin A)+c (sin A -sin B)= 0 .

Show that suma^3 sin(B-C) =0

In any Delta ABC,sum a(sin B-sin C)=a^(2)+b^(2)+c^(2)(b)a^(2)(c)b^(2)(d)0

Show that [suma^2 sin(B-C)]/sinA = 0

In Delta ABC, sum a (sin B-sin C)=

Show that sum sin (B + C) sin (B - C) = 0

Show that 4 sin A sin Bsin C = sin(A+B-C) + sin (B+C-A) + sin(C+A-B)-sin(A+B+C).
