Question 370646: I would like to know what the rule is for radians in terms of quadrants.
I already know the one for degrees:
Q1= Keep the Angle
Q2= 180 - Angle
Q3= 180 + Angle
Q4= 360 - Angle
So what are these 4 quadrants for radians?

You can put this solution on YOUR website!
360 degrees = 2%2Api radians
Divding each side by 2 we get:
180 degrees = pi radians

Now, in your four equations for the quadrants, replace the 180's and the 360 by pi and 2%2Api, respectively.
