If \(A, B, C\) are the angles of triangle then \(\sin 2 A-\sin 2 B+\) \(\sin 2 C=\)
- A \(4 \cos A \cos B \sin C\)
- B \(4 \cos A \sin B \cos C\)
- C \(4 \cos A \sin B \sin C-1\)
- D \(4 \sin A \cos B \sin C\)
Answer & Solution
Correct Answer
(B) \(4 \cos A \sin B \cos C\)
Step-by-step Solution
Detailed explanation
Given that \(A, B, C\) are the angle of triangle \(\Rightarrow A+B+C=\pi \Rightarrow 2 A+2 B+2 C=2 \pi\)...(i) Now,…
