from the intervals 0 less than or equal to theda less than 2 pie, what is cot theda of 2
Do you want the angle whose cotangent is 2? That would be written
It is the same as the angle(s) with tangent 1/2.
Since you want it in radians, it is 0.4636 radians in the first quadrant of pi plus that number in the third quadrant.
