Any key, or click. Only the first few slides are important, the rest are just me suffering. Original description preserved for historical purposes or something (it's solved now): Okay, so this is a math problem my friend came up with, that I call "The Textbook Problem". So far, it is unsolved. You're stacking rectangular textbooks, corner-to-corner, with the opposite corners touching. How many must you stack before you get a book the same orientation as the first? The books we used were standard U.S. paper size, 8.5/11, but I want to know a method where you can plug in any side lengths & figure out an answer without actually having the physical books. Sometimes it may look very close, but not be the same orientation. So solving this with physical books doesn't work. I want to be exact. It doesn't sound so hard, does it? Ha. Haha. Ah ha haha. AhahahahahHAHAHAHAHAHAHAHAHAHAH. I have been pondering this problem for months. ._. Alternative name for this math problem: "The Rectangles of Sadness". So anyhow. I'm looking for help solving this. It's not homework or something; it's just a pet project. Any help is welcome & appreciated!
