The Attempt at a Solution
The 1st part is easy, I wrote:

But I can't do the second part, I read about 10 different sources about these unit vectors, but now I'm even more confused. Especially about so called "radial" and "transverse" unit vectors, they are not "tangential" and "normal" unit vectors?
Anyway, for this part I tried analytical approach:

But not sure what to do next. Or another approach:

Any help will be appreciated, I spent about 2 days on this problem alone
