We update the list of Zoom meetings each week.
I started XYZ Textbooks when the publisher I was with at the time, priced my trigonometry book at $320. I asked them repeatedly to lower the price. The would not do it, so I started my own company to offer quality textbooks at reasonable prices. This year we are publishing a version of trigonometry and the price for the print book is $50. The eBook is $45. It is the best deal for trigonometry anywhere.
