JEE Math Practice Question
Let $${{\sin A} \over {\sin B}} = {{\sin (A - C)} \over {\sin (C - B)}}$$, where A, B, C are angles of triangle ABC. If the lengths of the sides opposite these angles are a, b, c respectively, then :
- A.b2 $$-$$ a2 = a2 + c2
- B.b2, c2, a2 are in A.P.
- C.c2, a2, b2 are in A.P.
- D.a2, b2, c2 are in A.P.
