    Question

    If (2sin A + cos A) = 3sin A, then find the value of cot

    A.
    A 1 Correct Answer Incorrect Answer
    B (3/2) Correct Answer Incorrect Answer
    C √2 Correct Answer Incorrect Answer
    D √3 Correct Answer Incorrect Answer

    Solution

    We have, (2sin A + cos A) = 3sin A

    Or, cos A = (3 - 2) sin A

    Or, cos A = sin A

    Or, {(cos A)/(sin A)} = 1

    So, cot A = 1

    Hence, option a.
