Prove it for a triangle ABC:- i> ((cosA)/a)+(a/bc)=((cosB)/b)+(b/ca)=((cosC)/c)+(c/ab) ii> a 3 sin(B-C)+b 3 sin(C-A)+c 3 sin(A-B)=0 iii> (a 2 sin(B-C)/sinA)+(b 2 sin(C-A)/sinB)+(c 2 sin(A-B)/sinC)=0 I am eagerly waiting for the reply!!!!!

Prove it for a triangle ABC:-
i> ((cosA)/a)+(a/bc)=((cosB)/b)+(b/ca)=((cosC)/c)+(c/ab)
ii> a3sin(B-C)+b3sin(C-A)+c3sin(A-B)=0
iii> (a2sin(B-C)/sinA)+(b2sin(C-A)/sinB)+(c2sin(A-B)/sinC)=0
I am eagerly waiting for the reply!!!!!
