  Hi @skadam ! A Cylindrical Coordinate System is one of the coordinate systems (CS) which is represented in terms of r, theta and z. Here, r is radius from the axis, theta is angular position and z is height.
  We can use Cylindrical CS in the cases where we have cylindrical symmetry like rotating equipments, electric charges, etc.

  Thanks @akhemka , I have one follow up question.
  How can we relate Cylindrical CS with Cartesian CS?

  The Cylindrical CS is related to Cartesian CS in the following way;
  r = sqrt(x^2 + y^2)
  theta=inverseTan(y/x)
  z=z
