Calculus practice
Hello. Where can I find some extra practice with the concepts introduced in Spivak's Calculus, the book used in my class, so I can solidify my understanding? (I'm looking for a book or a website) These should have answers and solutions easily accessible. I'm looking for a coverage that is about the same scope as the textbook, but more problems; Spivak doesn't really give practice in the problems at the end of the chapters, he uses them to make you think or introduce new concepts, but I need to gain a grasp on the old concepts first! 24.92.70.160 (talk) 01:30, 18 December 2010 (UTC)
 * That is a pretty theoretical book, sort of halfway between a calculus book and one on real analysis. What concepts are you having trouble with, and what kind of trouble are you having?  If you're having calculational difficulties, try something like a Schaum's outline (they are often better than they sound).  Wikibooks also has a calculus book in progress, Calculus, some parts of which are pretty good. 67.117.130.143 (talk) 09:09, 18 December 2010 (UTC)

Nonogram constant
Is there a “nonogram constant”, which appears in the order of growth of the number of all n×n-nonograms with a unique solution? --84.61.182.248 (talk) 12:18, 18 December 2010 (UTC)
