Hello, thanks for the video. I wanted ask: at 4:20 you say: we can express the location of point P in polar coordinates as: vector(r) = r u_r. Ok but in figure our frame has origin into the point P; should not be in point O, so as to say that we multiply the r with the u_r and have exactly the vector r with respect to the frame?
