• Calculus 'Good Questions' at Cornell
  An NSF-funded project for Calculus education. Includes a wealth of questions, listed to correspond to the Stewart text, and denoted according to difficulty (Q = Quick, P = Probing, D = Deep).
  
  
• Interactive Online Math Tests, and Galery of Multimedia Learning Units.
  A wonderful wealth of quizzes and java tutorials on calculus, elementary functions, elementary algebra, and even minkowski spacetime. Easily adapted to classroom. Part of the Math Online site at the University of Vienna website. NOTE: Math notation will not appear correctly unless viewed on Internet Explorer.
  
  For those with a bent for programming or developing: It would be nice if the applet "the graphs of sin, cos, and tan" on this page also allowed you to use different figures than just the circle; check out the top slider on the applet "quadratic equations 2" on this page--it would be great if they had the same thing for higher-order polynomials; it would be nice if, on the first applet "on the definition of the derivative" on this page, you could do different functions; on the applet on this page it would be nice if you could drag the line to have a different slope, and also to change the line to some other functions. Also very cool are the sequence and series calculators on this page.
  
  
• True/False Math Questions
  sometimes surprisingly tricky concept-type questions, ranging from precalc to calc, also with some prob/stats and other higher-level math. Very good stuff here. Part of the extensive finite math and applied calculus resource page at Hofstra University.
  
  
• False math proofs
  From internet humor lists (scroll down the page). Useful classroom aids for things like improper rearrangement of infinite series, forgetting the constant of integration, and the like.
  
  
• Find the Error
  Eleven calculus errors (without solutions!). Good for homework exercises.
  
  
• Common Errors in College Mathematics
  By Eric Schecter, at Vanderbilt. Lengthy. Some simplistic stuff, but also some interesting difficulties with limits and calculus (also has the answer to some of the errors in the Find the Error link above!) Best viewed with Internet Explorer.
  
  
• Project: The derivative of an integral
  A math-reform type project (with instructor 'answers') illustrating one half of the fundamental theorem of calculus. Nice intuitive geometric arguement.
  
  
• "20,000 Problems Under the Sea".
  A searchable collection of twenty-thousand math problems, culled from student math journals and competative examinations. Potentially useful for math teachers.
  
  
• Practice college math placement tests.
  Three practice placement tests, one for college algebra, one for pre-calculus, and one for calculus; from the math department at University of North Texas.
  
  
• "Problems to enjoy"
  A repository of math problems with solutions, at the primary school or high school level, mostly of the number-theory/geometry flavor.
  
  
• Analysis problems.
  Math-grad level exam problems, compiled by Saeed Zakeri, a visiting professor at Stony Brook.
  
  
• Harvard Physics Problem of the Week
  Fifty-four mathematical problems, at the upper-undergrad level. With solutions.

• National Library of Virtual Manipulatives (NMLV)
  An NSF-funded project at Utah State University. Contains dozens of java-applets of arithemetic, geometric, and pre-calc level concepts, including this wonderful java applet function graphing utility with a slider for free parameters, and this histogram grapher, allowing your own data, and with a slider for bin width
  
  
• Searchable online 'Math tools' database
  At Drexel Mathforum. Use the pull-down menus at the top of the page; allows you to search for applets and other resources, by type (e.g., algebra; calculus; statistics).
  
  
• Manipula Math
  Many pages of applets on math topics ranging from Pythagorean Theorem (9 different proofs in all of this) to dot product and complex numbers.
  
  
• Math and Physics Applets
  By Paul Falstad. Some interesting java applets on such topics as the action of matrices, the vector dot product, and many physics topics; plus links at the bottom.
  
  
• "Demos With Positive Impact"
  A collection of calculus-oriented demonstrations (mostly computer, but some physical), by Lila Roberts of Georgia Southern University.
  
  
• Calculus Graphics by Doug Arnold
  Eleven sets of computer-generated graphics pertaining to simple calculus themes, like the tangent line, volumes by slices, and bouncing ball producing infinite sum. These are some of the first (from 1997) such graphics online, and they're now an internet classic.
  
  
• the mathserve calculus toolkit
  simple online graphers, root-finders, and various pre-calc and calc-1 material, using Mathematica engine, hosted at Vanderbilt. The real value for educators is that the graphs automatically generate a gif image that can be copied into a handout (and the graphing range can be controlled). Also, the Newton's method page outputs multi-decimal approximations for various steps; useful for checking text solutions.
  Note: The Vanderbilt directory has changed, and these links do not seem to work anymore.
