The first group of questions only require a scientific calculator.

The second set, at this point your text expects you to have an intimate knowlege of the special angles. Read This:

Trig Values of Special Angles
Exact Values of Trig Functions
Certain angles have trig values that may be computed exactly. Of these, the angles listed below are some of the angles most commonly used in math classes.

All these problems can be solved using the above table in tandem with the identities found in the unit circle.

To have the best understanding of these problems you should avoid using your calculator. (Nerd)

You're jumping the gun wanting to get help with so many questions - questions that your son has yet to learn how to do at school. When your son starts learning this stuff (next month) this thread will make sense for him.

Until then, your son should be getting support in the things that he is currently learning or has already learned since that stuff will be getting built upon.
