Angular displacement

Well of course it's angular rotation, but the key
difference in math, as opposed to engineering and physics is that while the latter measure angles in
degrees(360 to a circle) , in math we measure it in
radians. A radian is the angle required to subtend
an arc length equal to 1 radius. That would be an
angle of exactly 360/(2pi) or approx 57.3 degrees.
Some commonly known angles we use and their radian equivalence are
360 2pi
180 pi
90 pi/2
270 3pi/2
45 pi/4
60 pi/3
30 pi/6

amount of rotation = moment of inertia x angle speed
moment of inertia = p x mass x radius^2

This would be the rotational angle, commonly represented by one of the Greek letters theta, phi or psi.

Rotational angle is the mathematical term for amount of rotation.
It is generally denoted by theta.It is measured in degrees.

If you are thinking about how fast something rotates it would be frequency.
