Tricki now online
After a short pre-live test, Tricki is online now. It is a repository for problem solving techniques and nifty tricks in mathematics. Although it just went live and is based on the same principle as other wikis (and thus has to grow over time) it looks very promising already. You should definitely check it out!
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 every level 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 you may wish to begin by investigating the following links, which 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.
