Homework Statement
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?
Homework Equations
y = r sin (phi)
j = r(hat)cos (phi) - phi(hat) sin (phi)
The Attempt at a Solution
THe relations are right there but I've forgotten howto use them.
