Circular Functions Part 2 of 3

[SPRAZE13]

I have problems understanding the concept of let's say 7pi/3 going all the way around a circle. How could someone know that?

[FrenchFootballLegend]

@SPRAZE13 ok well an entire loop around the unit circle is equal to 2pi. 3pi/3 is equal to pi, which is 180 degrees around. 6pi/3 is double that amount, meaning it goes the full 360 around the unit circle. 6pi/3 reduces to 2pi. Now, since 7pi/3 is greater than 6pi/3, you can assume that 7pi/3 is going to go around more than once. In fact it is 6pi/3 + 1pi/3, so the point is now at 60 degrees but it has travelled 360+60 degrees. hope that helps even 4 months later lol
