<math> \sin(30) = 0.5 </math>
<math> \cos(60) = \sin(30) = 0.5</math>
<math> \sin(60) = \cos(30) = 0.866...</math>
<math> \sin(0) = \cos(90) = 0 </math>
<math> \cos(0) = \sin(90) = 1 </math>
<math> \tan(45) = 1 </math>
<math> \tan(0) = 0 </math>
<math> \tan(90) = \inf </math>

if <math> x + y = x^3 + y </math> then <math> x = 0 </math> and y is equal to anything :)
