It is angular displacement which may be measured in radians, or degrees-minutes-seconds. In 3-D it would be stradians

The side adjacent to theta divided by the hypotenuse, or the angle opposite of the right angle
r*theta = where theta is the angle measured in radians.= 5*120*pi/180 = 10.472 units (approx).r*theta = where theta is the angle measured in radians.= 5*120*pi/180 = 10.472 units (approx).r*theta = where theta is the angle measured in radians.= 5*120*pi/180 = 10.472 units (approx).r*theta = where theta is the angle measured in radians.= 5*120*pi/180 = 10.472 units (approx).
tan (theta x theta) : must square the value of the angle, theta, before applying the trig function, tangent.
Theta is the measure of the angle, whether in degrees or radians.
