The THETA function calculates the second angle (in radians) of a body-two fixed 3-1-3 Euler rotation sequence between markers i and j. Marker j defaults to the global coordinate system if it is not specified.

Format
THETA(i[,j])
Arguments
i | The marker whose rotations are being sought. |
j | The marker with respect to which the rotations are being measured. |
Examples
REQUEST/1, F2=THETA(222,434)
