Find the distance from pi.
7 pi/6. I subtracted 2 pi from this and got 5pi/6. But the correct answer is pi/6. Whwere did this come from?

MathMate,
If you are referring to reference angles, it is the acute angle that makes with the xaxis.
Since it is either 0 or 2π for the positive xaxis, or π for the negative xaxis, 7pi/6 makes π/6 with the negative xaxis, therefore the answer would be &pi/6.
If the question is not about reference angles, then you need to elaborate a little more.

Well in short pie means 180 degrees or 3.14 radians... subtracting 2 pie would be subtracting 360 giving you a coterminal angle here's how i would've worked the problem
5pie 180 = 150 degrees
6 * pie
that's 30 degrees away from pie or 180
30 2pie = 1pie
pie * 180 6
in short 30 degrees equals 1pie over 6 and that's how far your angle is away from 180 or pie

Christopher M. Boan,
the way it posted looks bad so I'm redoing the math with slash signs
5pie/6 * 180/pie = 150
30/pie * 2pie/180 = 1pie/6
