    Which of the following is possible?

    A) \[\cos \theta =\frac{7}{5}\]

    B) \[\sin \theta =\frac{13}{12}\]

    C) \[\sec \theta =\frac{4}{5}\]

    D) \[\tan \theta =41\]

    Correct Answer: D

    Solution :

    [d]\[\cos \theta \le 1,\,\,\sin \theta \le 1,\,\,\sec \theta \ge 1\]
    \[\Rightarrow \]a, b, c are not possible
    \[\therefore \,\,\,\,\,\,\,\,\tan \theta =41\] is possible.
