If A,B and C are the vetices of a triangle ABC, then prove sine rule (a)/(sin A)=(b)/(sin B)=(c)/(sin C)

Using vectors , prove that in a triangle ABC a/(sin A) = b/(sin B) = c/(sin C) where a,b,c are lengths of the ideas opposite to the angles A,B,C of triangle ABC respectively .

In any triangle ABC , prove that a sin A-b sin B -=c sin (A-B) .

For any triangle ABC, prove that sin(B-C)/sin(B+C)=(b^2-c^2)/(a^2)

Prove that in any Delta ABC,a(sin B-sin C)+b(sin C-sin A)+c(sin A-sin B)=0
