I'm confused about the distinction between surfaces and level surfaces also. *Comment*: It would be *much* easier to provide a reasonable answer if you provided a specific problem that you're working on with a specific function $f$.SpaceManSpiffWed, 09 Jul 2014 23:43:53 -0500http://calc3.askbot.com/question/77/
