Homework Statement
The angular displacement θ, despite having a magnitude and a direction, cannot be treated as a vector. This is because θ does not follow the commutative law of vector addition.
Does the infinitesimal displacement dθ obey the commutative law of addition and hence qualify as a vector? If so, how is the direction of dθ related to the direction of ω?
Homework Equations
The Attempt at a Solution
That θ does not follow the commutative law of vector addition can be proved easily using an example of two rotations of some object.
What I cannot prove is whether the the infinitesimal displacement dθ obeys the commutative law of addition. Any help on that would be greatly appreciated.
