1. The problem statement, all variables and given/known data Drawing surface ##f(x,y) = ...## or ##r(t) = <f(t),g(t)>## etc. 3. The attempt at a solution I've been working on drawing space curves lately, by breaking into separate planes and by level curves. I'm struggling w/ this topic. (1) If I'm not mistaken, this is fundamental in order to grasp the other topics within Multivariate and Vector Calculus, correct? (2) Are there any resources recommended for this topic, ANY help will be highly appreciated. Thank you.
