i^(4n+1)=i (I presumed n is integer) W/F means Work / Force and Work = distance (l) * Force (F) hence this is l rho=R means radius is constant in polar coordinate, hence it's a circle, represented by O x as position function, it's derivative w.r.t time is velocity, hence v the last limit is a basic result, it equals to e determinant = u
