You can use a unit circle to help you out http://etc.usf.edu/clipart/43200/43215/unit-circle7_43215_lg.gif locate the angle 2pi/3 and you'll be able to compute sin(2pi/3) and cos(2pi/3)

jimthompson5910 (jim_thompson5910):

to get tan(2pi/3), you divide \[\Large \tan(2\pi/3) = \frac{\sin(2\pi/3)}{\cos(2\pi/3)} = ??\]
