comment What is a diffeomorphism?
Sorry Muphrid but I can't accept your answer since I don't have enough rep here, I +1'd it though. I don't know why the question was migrated, I was only looking for a hand-wavy definition.

comment How does one create a rotation about a given axis in $R^{3}$ from rotations about the other axes?
This seemed to do the trick. Thanks @Shard !

comment How does one create a rotation about a given axis in $R^{3}$ from rotations about the other axes?
While it is a very nice result, I'm not sure it actually answers the question in that the matrix $\bf{R_{\hat{u}}}$ would appear difficult to decompose.

comment “Rules of thumb” to decide which convergence test is most appropriate
If the answer was helpful, please consider marking it as accepted, this will give more interest in the question (rep for you) and more interest in the answer (rep for me).

comment “Rules of thumb” to decide which convergence test is most appropriate
Although performing the integral test is a long-winded process, it always gives you a definite answer and so it is a powerful tool (although, are Maple or Mathematica xD).
