To prove that \( a \sin(B - C) + b \sin(C - A) + c \sin(A - B) = 0 \), we will use properties of triangles and trigonometric identities. Let's go through the proof step by step. ### Step 1: Write the expression We start with the left-hand side of the equation: \[ LHS = a \sin(B - C) + b \sin(C - A) + c \sin(A - B) \] ...
