Unless you are really comfortable with radians, some students find it easier to think in degrees
7pi/12 = 105º = 90+15
so we are in the 2nd quadrant
estimate and divide the 2nd quadrant right-angle into thirds, that would make each 30º
Now divide the first of those from the vertical in half making that angle 15º
So the 90 from quadrant I plus that 15 makes 105º or 7pi/12 radians
7pi/12 = 105º = 90+15
