    Dude you're a literal lifesaver. My precalc teacher uses the "teach yourself completely foreign concepts and if you don't get it right away I'll bitch at you and if you ask questions I'll send you to the office" method so needless to say receiving instruction from her is a lost cause.

  • @TwinHunts

    Sir,
    Thank you very much for that fast response. I haven’t done this kind of math in over 10 years. I’m doing a review before I start Calculus.
    So with that said, I don’t have a trig book or the chart. Is there one online I could look up. If so, do you have a link.
