Consider the point P whose position in Cylindrical coordinates is: o p: 5' o 9: 7rlarctan(4/3), o z: 12 In Cartesian coordinates, this is (draw this on a piece of paper. This is easier if you don't use a calculator If you aren't able to nd a: and 9 without a calculator, then please come to ofce hours/maths hub) =E =:l IKE If r (P) IS the vector from the origin to P then in terms of the unit vectors at P P) =EEP+E69+E The length ofF(P) is urn =E
