    Trigonometric Tables and Formulas

    I'm looking for any page to print so I can know the exact sines, cosines, and tangents of common angles. If anyone could link me to a page so I can find these it would be very much appreciated. Thanks in advance.

    Use the unit circle. It's much easier to remember the two triangles (1, 1, sqrt(2)) and (1, sqrt(3), 2) than it is to remember the nine common values.

    Got something that I could print out? Anything really at this point will help. I have a trig final next week and it's open resources. Just need anything at this point.

    Edit: Thanks Mafai, just what I was looking for.

    Send Woozie or Kaylia a pm. They have a few really neat math references that should be of help to you.

    Edit: Or you can post your question here if this falls off the first page by time they log on. That thread is everything science and math related for the most part.

    Mother fucker shut up. Only math question you should be answering is how many ounces are in a 40.

    Unit circle makes this shit sooooooooooooooo easy, easy to memorize, just memorize the position of the QII and the rest fall into place

    If you're writing a program, consider using Taylor Series Approximation unless you need absolute precision. The performance cost is significantly lower.

    Could you possibly whiten that up a little so I can understand what you're saying? I feel I should warn you. I don't "run" with those "crippies" so if that was a threat I'll meet you on the back nine at the course for a rousing skins game to settle the score.

    Math tutor here,

    Just wanted to weigh in noting that it's easier to remember unit circle sines and cosines if you consider ALL of those as one half the square root of the first few integers. So for degree measurements:

    sin(0) = sqrt(0)/2 = 0
    sin(30) = sqrt(1)/2 = 1/2
    sin(45) = sqrt(2)/2
    sin(60) = sqrt(3)/2
    sin(90) = sqrt(4)/2 = 2/2 = 1

    It then returns to 0, then down to -4, then back to 0 again to complete the circle. Cosine is almost the same but it starts with 4, goes to 0, -4, 0, back to 4. Sorry I don't have a picture or anything but just check out the unit circle pics in posts above mine and compare to what I'm trying to say.

    Holy crap, I wish they taught it that way in high school lol. I used to have so much trouble remembering those.

    Yeah if you look at the pic he posted, you will see the pattern.... you damn kids and the internet. I had to figure out how the relationship worked myself. My teacher never described it in the way that picture does.

    Most texts, in more advanced mathematics, use those common angles for the examples used. It is worth while to realize and then memorize those relationships. The less you need to concentrate on figuring out those exact values, the more time you can spend figuring out the more advanced relationships.

    I ended up memorizing the values because we used those angles a lot in the lower level physics classes. After you use them a kajillion times they sort of stick. But things would have been so much easier back then if I had just known that pattern. I can't believe I never even noticed it @_@

    I'm not trolling, I can't think about a trigonomy equation/result that I used that wasn't on wiki before.



    Anyway, the best things would definitively be a circle with the angle listed like Tenjou said. It would be easy to draw one in paint.

    Otherwise, the one pirian posted should works, since it worked for all of us before.

    No kidding, I had the same though.

    Real men just draw special angle triangles and figure it out from scratch.

    Seriously though, am I the only person who does this? I suck at memorizing things.

    That's what I did when I wasn't able to use a calculator (i.e. high school trig), but now I use one to make sure I don't make a mistake.
