Homework Help: Trigonometry cos A + 1

    [SOLVED] Trigonometry cos A + 1

    My little sis needs help w/ the following problem for her homework and to tell you the truth, aside from the fact that I'm too busy I have no idea how to explain this to her step by step. I would appreciate an explanation on how to solve it -- a solution would be fine but even just the steps for solving it would be appreciated. thanks.


    1. The problem statement, all variables and given/known data

    Reduce
    (cos A + 1) / cos A

    The only thing I can see is the obvious:
    [tex]\frac{cos A+ 1}{cos A}= 1+ \frac{1}{cos A}= 1+ sec A[/itex]
