We return to precalculus tomorrow and throughout the weekend but, like I said in our most recent PM, I will post questions that
A. I tried over and over again to solve but to no avail and B. questions that I simply have no idea what to do.
P. S. Look for my occasional David Cohen questions from time to time. By the way, I had no idea that David Cohen passed away years ago from leukemia. I guess we are not leaving this world alive.
