I watched a webinar by Dr. Robert J. Lopez, titled "Algebra, Trig, and Precalculus Math – All by Syntax-Free Maple".

In it he says he will give his email at the end if anyone wants the worksheet he is using during the webinar.  

I don't think he ever gave his email and, as a Precalculus teacher, I would really like the worksheet.  Please advise.
