Talk:Exact Trigonometric Values

Try Trigonometric Constants.

Previously this link pointed to a good list of exact trigonometric constants. Now it is redirected to virtually nothing like the previous target of the link. It's unfortunate that the custodians of Wikipedia have such a cavalier attitude to the arbitrary deletion of good information. This is why I felt it necessary to create this page.

It has happened again. The following was a good link. Cosine of 36°.

Now it goes to nowhere.
