**Bosnian**, Saturday, April 7, 2012 at 2:22pm19 pi / 7 =

( 14 + 5 ) * pi / 7 =

( 14 / 7 ) pi + ( 5 / 7 ) pi =

2 pi + ( 5 / 7 ) pi

2 pi + theta = theta

I quadrant 0 ÷ pi / 2

II quadrant pi / 2 ÷ pi

III quadrant pi ÷ ( 3 / 2 ) pi

IV quadrant ( 3 / 2 ) pi ÷ 2 pi

theta = ( 5 / 7 ) pi

theta = 0.7142857 pi

thheta > pi /2

theta < pi

II quadrant

**Reiny**, Saturday, April 7, 2012 at 2:29pmSome students can see this better when visualizing it in degrees

19π/7 radians = 19(180)/7 ° = 488.57..°

= co-terminal with 488.57-360 or 128.57..°

which would be in quadrant II
