ORIENTATION OF A RIGID BODY
Eulerian angles:
X,Y, Z and are a fixed inertial frame.
let x, y, z and i, j, k be fixed to the body such that it will move with the body.
First motion:
Second motion:
Third motion:
For this to be useful, we need to operate in the same unit vector system.
Let us keep our notation short by denoting sin as S and cos as C.
As now,
This is the rotation w.r.t the moving body. We can do the same procedure and find the rotation w.r.t. the fixed (inertial) frame:
We can break up the rotation as:
We can use these to solve for the rotation of each
