In another math site, someone reported that math professor David Cohen is dead. I had no idea that Mr. Cohen passed away. Is this true? Is David Cohen no longer with us? I have his Precalculus With Unit Circle Trigonometry 3rd Edition textbook. In fact, it is my favorite math textbook by far and a book I have been using for years.
