      Question

      If asinx +b cosx = c then find the value of acosx -

      bsinx =?
      A тИЪ(a┬▓+ b┬▓-c) Correct Answer Incorrect Answer
      B тИЪ(a┬▓- b┬▓-c┬▓) Correct Answer Incorrect Answer
      C тИЪ(a┬▓+ b┬▓+c┬▓) Correct Answer Incorrect Answer
      D тИЪ(a┬▓+ b┬▓-c┬▓) Correct Answer Incorrect Answer

      Solution

      (a sinx+ bcosx)2 +(a cosx - bsinx)2 = a2+ b2 OR (c)2 +(a cosx - bsinx)2 = a2+ b2 OR (a cosx - bsinx)2 = a2+ b2 - c2 OR a cosx - bsinx =┬а
