The Attempt at a Solution
I have found expressions for the unit vectors for cylindrical coordinates in terms of unit vectors in rectangular coordinates.
I have also found the time derivatives of the unit vectors in cylindrical coordinates. However, I am having trouble seeing how it simplifies. For instance, I do not understand how to arrive at the following for the rho hat unit vector.
Can someone enlighten me, please?
