In a triangle `ABC`, if `a,b,c` are the sides opposite to angles `A`, `B`, `C` respectively, then the value of `|{:(bcosC,a,c cosB),(c cosA,b,acosC),(acosB,c,bcosA):}|` is

In a triangle ABC, if a,b,c are the sides opposite to angles A,B,C respectively,then value of |(bcosC,a,c cosB),(c cosA,b,acosC),(acosB,c,bcosA)| is a)1 b)-1 c)0 d)a cos A + b cos B + cos C

In triangle ABC if a,b,c are sides opposite of angles A, B, C respectivgely, then which of the following is correct ?

In a triangle ABC , bcosc +c cosB is:

In a DeltaABC, a,b,c are the sides of the triangle opposite to the angles A,B,C respectively. Then the value of a^3sin(B-C)+b^3 sin(C-A)+c^3 sin(A-B) is equal to

In Delta ABC,a,b,c are the opposite sides of the angles A,B and C respectively,then prove (sin B)/(sin(B+C))=(b)/(a)

If a,b,and c are the side of a triangle and A,B and C are the angles opposite to a,b,and c respectively, then Delta=|{:(a^(2),bsinA,CsinA),(bsinA,1,cosA),(CsinA,cos A,1):}| is independent of

If a,b,and c are the side of a triangle and A,B and C are the angles opposite to a,b,and c respectively, then Delta=|{:(a^(2),bsinA,CsinA),(bsinA,1,cosA),(CsinA,cos A,1):}| is independent of
