My quick tip for bullshitting through trig functions: Teachers will basically always only give you degrees in sin and cos in units of 45 and 30 (so 30, 45, 60, 90, and so on). Now, you throw that into your calculator, and you get more or less three different results, 1/2, sqrt(3)/2, or sqrt(2)/2. Use that. When you get sin(45) throw that into your calculator, and you get something that looks like .707 whatever garbage that your teacher isn't happy dealing with. So, then you say put sqrt(3)/2 in the calculator, and you get .866 whatever. So that's not it. Then put in sqrt(2)/2, and it's .707 whatever. There you go, you say sin(45) = sqrt(2)/2, and then move on in your problem. It takes a bit longer, but you have to memorize less stuff. Figure out what the degrees look like in a circle (as in, what 135 degrees look like), throw some negative numbers around, and call it a day. Proofs, there's no easy way of making those easy. Just think "why is this true", and do some math. Normally it's 80% setup, and 20% being creative. --- ImmortalityV, "I would like to kiss Icoyar to be honest in a non gay way though" ...
