Meridians and Circles of Latitude of a surface of revolution

Click For Summary
SUMMARY

The discussion focuses on identifying the meridians and circles of latitude for a surface of revolution defined by the parametric equations ##X(t, \theta) = (r(t)cos(\theta), r(t)sin(\theta), z(t))##. The meridians correspond to the ##t##-curves, while the circles of latitude correspond to the ##\theta##-curves. To visualize these curves, one fixes either the parameter ##\theta## or ##t## and examines the resulting image of the function ##X##. This understanding is crucial for solving problems related to surfaces of revolution in multivariable calculus.

PREREQUISITES
  • Understanding of parametric equations in multivariable calculus

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##?

Yes. Some texts call them parameter curves.
