Dear all, 

I am trying to use the Physics package to perform a simple computation about the expression of speed and acceleration in the local polar basis (Frenet). I am trying to get something like :

Define the position vector :

differentiate wrt t to get the velocity vector 

simplifying 

 

Similarly :

 

simplifying

Can anyone please help me ? Many thanks!
