Topic, The topic where you can only post the most random things you can think of that doesn't make sense... | ||||||

But what shall we make. You often post algebraic problems, but they're usually linear which can be solved by collecting like terms and dividing through to get a singular variable. I posted a couple of polynomial equations which are a bit more challenging (I would post other stuff, but you mentioned calculus wasn't your strong suit and a geometry question may be too wordy to be practical, though some of those questions can be quite nice). I could post more difficult questions, but this is a game site, not a mathematics blog so I'm not sure there would be nearly enough interest. In any case I have one that is kind of interesting. Evaluate the closed formula for the following finite sum: 1+2+3+...n. That's a question that shouldn't be too annoying, it's more interesting to see the method, because I know what I might try but others are different. Formula to find: Here's how I did it (in my head but I've written down my thoughts). 13×19×37 4219 3²×7×13 2²×11×13 17×131 2²×3²²×11 2²×3×5×17 37×523 3×6653 19993 2×3²×7×139 2²×13×337  | ||||||
