<p>how do you guys go around memorizing the special trig angles? ie cos pie/3 = 1/2, etc. </p>
<p>there are so freakin many...any secrets you wanna share?</p>
<p>theres a simple way to memorize these... sin 0 = 0, sin pi/6 = 1/2, sin pi/4 = root2/2 ... if you see the trend you add one in the square root in the numerator while keeping the denominator at 2... and cos is opposite</p>
<p>If you've ever memorized the special 45-45-90 and 30-60-90 right triangles, you can also derive them from those.</p>
<p>Rhapsody in Green... That is what I'm doing... I'm too lazy to memorize those angles..
or.. plug in the calculator..</p>
<p>You don't have your calculator for parts of the test. There are so many tricks to memorizing the special angles. I use the root one mentioned above and also this weird hand one.</p>
