Frames and monogram notation

Controls

θ_T (rotation of T about the world z axis): 30°

Decompose the arrow T→M along: T's axes W's axes

mug attached to the tray (moves with it)

quiz mode (hide the numbers of the arrow T→M)

Readouts

The three readouts of the arrow tray→mug describe one arrow. Only the subscript, the frame whose axes the numbers are written in, changes. With the mug attached, turning the slider leaves ^Tp^M_T unchanged and changes ^Tp^M_W and ^Wp^M.

Default state = the worked example of the session 2.2 notes §5: T at (0.40, 0.20), θ_T = 30°, mug at (0.15, 0.05) in T. Companion notes: notes.md.
