This is the pre-live version of the Tricki. The Tricki is still under development and not yet open to the public.
Welcome to a brand new Wiki-style site that is intended to develop into a large store of useful mathematical problem-solving techniques. Some of these techniques will be very general, while others will concern particular subareas of mathematics. All of them will be techniques that are used regularly by mathematical problem-solvers at all levels of experience. We hope you will enjoy using the site and that many people will contribute to it. If you are new to the Tricki, then clicking on the following links will take you to more detailed discussions of what the site is, what we hope it will eventually become, how to contribute, how to edit existing contributions, how to make comments, and more.
