Is the relationship ∆ϕ 1 + ∆ϕ 2 = ∆ϕ 2 + ∆ϕ 1 valid if ∆ϕ 1 and ∆ϕ 2 refer to different axes of rotation? Is it valid if they refer to different rotations about the same axis?

Is the relationship ∆ϕ1 + ∆ϕ2 = ∆ϕ2 + ∆ϕ1 valid if ∆ϕ1 and ∆ϕ2 refer to different axes of rotation? Is it valid if they refer to different rotations about the same axis?

It can be seen from the figure above that the book is rotated about the x axis twice by 20° . One can observe that the commutative law of addition remains validated when the axis of rotation is kept same.
