" 7."(sin(A-C)+2sin A+sin(A+C))/(sin(B-C)+2sin B+sin(B+C))" is equal to "

(sin(A-C)+2sinA+sin(A+C))/(sin(B-C)+2sinB+sin(B+C)) is equal to-

(sin(A-C)+2sinA+sin(A+C))/(sin(B-C)+2sinB+sin(B+C)) is equal to

(sin(A-C)+2sinA+sin(A+C))/(sin(B-C)+2sinB+sin(B+C)) is equal to

(sin (AC) + 2sin A + sin (A + C)) / (sin (BC) + 2sin B + sin (B + C)) is

Prove that: (sin(A-C)+2sin A+sin(A+C))/(sin(B-C)+2sin B+sin(B+C))=(sin A)/(sin B)

In triangle ABC,(sin A+sin B+sin C)/(sin A+sin B-sin C) is equal to

sin(B+C-A)+sin(C+A-B)+sin(A+B-C)=4sin A sin B sin C

Simplify: (sin(A - B))/(sin A sin B) + (sin(B - C))/(sin B sin C) + (sin (C - A))/(sin C sin A)

Prove that (sin (A - B))/( sin A sin B ) + ( sin (B -C))/( sin B sin C ) + (sin (C - A))/( sin C sin A) =0
