1. The problem statement, all variables and given/known data A position vector (between the origin and point (5,2,3) is expressed as r=5(x hat) + 2(y hat) + 3(z hat). Express vector in cylindrical coordinates. RHO = SQRT(5^2 + 2^2) FIE = tan-1(y/x) Z=3 Clearly, RHO = 5.385, FIE = 21.8, and Z=3. The answer is given is only 5.385(RHO hat) + 3(z hat) What is the FIE not included in the final answer?
