    Question

    Find the value of (1 - sin2q) X (secq + tanq)

    X (secq - tanq) X cosec2q
    A sec²q Correct Answer Incorrect Answer
    B tan²q Correct Answer Incorrect Answer
    C cot²q Correct Answer Incorrect Answer
    D sin²q Correct Answer Incorrect Answer

    Solution

    (1 - sin2q) X (secq + tanq) X (secq - tanq) X cosec2q = cos2q X (sec2q - tan2q) X cosec2q = cos2q X (1/sin2q) = cot2q
