    Difficult Trigonometry (3 Problems)

    I'm needing some help figuring out how to begin working these problems. I don't very much understand this section of Trigonometry.

    It is not the function of this HELP-SITE to offer a walk-through.
    You have shown any effort on your part. You may need a private tutor. If that is the case, then you need to look else where.
    You post work and we help you understand
    The first set of questions are simple half-angle questions.
    Show some effort.
    Thanks from topsquark

    Well, I will rephrase my question. Thank you for helping me with the half-angles part.
    I have no one to tutor me.
    Sorry for the intrusion.

    In the future, please post only one question per thread. It just gets messy this way.

    For the first attachment maybe it would help for you to tell us what the half-angle formulas are for tangent and cosine?

    Re: Difficult Trigonometry (3 Problems)

    for question 16 - (a)

    here is the half angle formula for tangent



    or



    you can use either one, then



    Just leave the answer like this since the question mentioned that no need to simplify.

    for (b) use half angle formula for cosine and follow same style
    (c) is similar to (a) just modify the angle
