I’ve been reading one of my old calculus books (Thomas/Finney Calculus and Analytic Geometry 7th Edition). It’s amazing how much I used to know, eh? Other than to remind myself with how stupid I have become, I wanted to register for a free internet thing, but as part of the process, one had to answer a random math question (brilliant idea, really), and, duh, I couldn’t remember some “basic mathematics” as my East German 4th semester calc prof termed it.
On the positive side, it didn’t take me that long to figure out the problem with the text in hand. I haven’t completely entered my dotage yet.
