I added a notebook but the preview looks unreadable. The notebook shows two seemingly identical computations giving different answers. I'm posting to see if the post is readable. If so, perhaps someone could comment.
Thanks, Leon
I think I may know what caused the problem. Usually, I set the notebook's default context to "unique to this notebook". I left one notebook in global context. That notebook had a different formula for p(x) than the one in the new notebook.
You are very generous. I have you to thank for resolving this. Thank you.
I am VERY impressed! I thought it might likely be the case that you would never be able to track down the real reason for this. You taught me and you and perhaps others one more thing to watch out for. Congratulations and thank you.
You were right. After restarting Mathematica and executing the Clear the two formulas agreed. I will continue to investigate. Thanks!
