title: How do Trigonometric functions work?
body: <p>So in high school math, and probably college, we are taught how to use trig functions, what they do, and what kinds of problems they solve. But they have always been presented to me as a black box. If you need the Sine or Cosine of something, you hit the sin or cos button on your calculator and you're set. Which is fine.</p>
  
  <p>What I'm wondering is how trigonometric functions are typically implemented.</p>
