Question

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

    A √(a²+ b²-c) Correct Answer Incorrect Answer
    B √(a²- b²-c²) Correct Answer Incorrect Answer
    C √(a²+ b²+c²) Correct Answer Incorrect Answer
    D √(a²+ b²-c²) 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 =
