Express the direction 331° CW from the +xaxis in the following different ways. For this problem north is positive y and east is positive x.
1) east of north
2) above the +xaxis
3) right of the vertical in quadrant 1
4) CW from the yaxis

331°CW from the +x axis is the same as 360°331°=29° in the trigonometric sense, namely 29° CCW measured from the +x axis, in the first quadrant.
1. To get the angle "east of north", subtract 29° from 90 (north).
2. The angle is 29° above the xaxis.
3. right of the vertical is the same as #1 above.
4. CW from the +y axis is the same as #1 above.
