That's a nice reference article, Joe. It may have also come in handy during another recent discussion where trig functions and \(\pi\) were being discussed to show the rationale behind some of the non-CAS results (even if they weren't agreeable). You have an amazing amount of historical info stored away in your head! Thanks for sharing it with us.
