    ok imagine that you just got diagnosed with a bad case of Trig, then this is a band aid. You're going to have to remember these eventually and this will help you get started. DON'T RELY ON IT! If you do then your Calc professor will be an angry person at you and your trig professor. You're going to have to know these exact values. Remember its a reference not a babysitter.

    Good reference tool. Good unit circle and plenty of formulas. Could use a place for notes. The biggest problem is that it is not zoom-able and formats small on tablets. Otherwise very handy.

    This Trigonometry Quick Reference cost me nothing, so 2 Stars. Quite a bit of reference for Trig, but just that. I am not being too critical here.
