## Homework Statement

Find the meridians and circles of latitude of a surface of revolution ##X(t, \theta) = (r(t)cos(\theta), r(t)sin(\theta), z(t))##.

## Homework Equations

## The Attempt at a Solution

I honestly just need a definition of what these concepts are. My book, as an aside for this specific homework problem, just says they are the ##t##-curves and ##\theta##-curves respectively. Does this mean I fix ##\theta## and see what the image of ##X## is, and then vice-versa for ##t##?
