(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Say I have line, y = - 5 in cartesian coordinates. How do I express this in cylindrical coordinates?

Also, if I have a point (0,-5) in cartesian coordinates, how to I express this position vector in cylindrical coordinates?

2. Relevant equations

y = r sin (phi)

j = r(hat)cos (phi) - phi(hat) sin (phi)

3. The attempt at a solution

THe relations are right there but I've forgotten howto use them.
