Suppose you are looking at a field [m[x,y],n[x,y]] which has one singualrity at a point P and no other singularities. While studying the singulairty, you center a circle of radius r on the point P and no other singularites. While studying the singularity, you center a circle of radius r on the point P and parameterize this circle in the counter-clockwise direction as Cr;{x[t],y[t]}. You calculate (integralCr) -n[x[t],y[t]]x'[t] + m[x[t], y[t]]y'[t]dt and find that it is equal to -1 +...

Your task will be to derive the equations describing the velocity and acceleration in a polar coordinate system and a rotating polar vector basis for an object in general 2D motion starting from a general position vector. Then use these expressions to simplify to the case of non-uniform circular motion, and finally uniform circular motion. Here's the time-dependent position vector in a Cartesian coordinate system with a Cartesian vector basis: ⃗r(t)=x (t) ̂ i+y(t) ̂ j where x(t) and y(t)...
