I have a question that might be considered vague or even downright idiotic but just wanted to know that once we find out the velocity & acceleration of a body in angular motion in plane polar coordinates, and are asked to integrate the expressions in order to find position at some specified time 't' , would we proceed to integrate the velocity expression (say) like we do usually with respect to time when the said expression involves r cap as well as theta cap; since the polar unit vectors are not "fixed" unlike the unit vectors of i,j,k in Cartesian system?
