Which Polar Coordinates System Is This? by captainbangz: 3:51pm On Jun 25, 2021 |
Okay, I don't know exactly what type of Polar Coordinates System is this. I have Exams tomorrow, but I don't want to cram. Please anyone who is familiar with this should please tell me the exact topic...Have tried searching, can't find anything related. Only found the normal simple Polar coordinates system with resultant (r) and angle(theta).

The first one is rectantangular coordinate in vector form.it represent x and y axis denoting cos theta and sine theta respectively..... In field of dynamics,first derivative represent velocity and second derivative represent acceleration with respect to time.. The second one is three Cartesian coordinate system representing x,y,z or I,j,k respectively. The example given in mechanics problem,you determine unit or position vector and then use to calculate the moment of force abt a point in a particularl direction. |
