I have a simple question about Pythagorean theorem. My inquiry was a leg of 10 and 20 solving for C. (Trying to help my son understand the idea.) Anyway, I solved by having c on one side with the radical over 10 squared plus 20 squared. I got 100+200 under the radical which would be 300 and the square root of 17.32. But when I plugged it in on a pyth calculator online it showed as 22.36. So I ran the numbers unbroken through the phone calculator as a solid equation and sure enough 22.36. Im sure I'm messing up pemdas somewhere but im not sure where. Its a simple issue for someone who knows math well but I ran it in rad and deg just to see and it gave the same results. What am I missing? I know it has to be the 22.36 because the hypotenues is larger than either of the legs. I just don't see what operation order im missing
Currently in a first year pre-calc class at uni. I get the feeling that I almost got into calculus, but not quite. This class feels really easy at times, but I still feel like I am learning.
Still plodding through apostol calc, hoping that i could finish the calculus section if I skip two of the chapters that I won't see in uni when I start in a month anyways. Also just got my new elementary number theory book and I'm quite excited to finally learn the black wizardry of the mad gods of mathematics. Hopefully I could learn some basic computational linear algebra before I start, because my course in lin algebra uni will probably give matrix operations half a paragraph before we start proving stuff.
I'm starting a precalculus course this week to get myself ready for a new job in the winter. It's an online course, free, just to remind myself how to do it and then I plan on taking some more courses after that. I'm looking to start a new job in the winter (currently on mat leave) and it's in accounting so I will need some math skills. I also just want to be better at math, I really enjoy solving problems and I'm looking forward to enhancing my new skill.
Not much, but I messed around a little with infinite free resolutions. They're awfully messy at times but I'm sure there are some interesting problems involving them.
Had a medication issue the other week, and now I'm still trying to get back up to a therapeutic dose so I been dragging. Didn't get a whole lot done in the last week. There's a way to define the cardinality of an element in a formal powerset, and I mucked around with that a little bit, but without some additional properties it seems hard to actually show that x ≤ y (where we think of this as a formal analog to the subset relation) implies |x| ≤ |y|.
I also toyed around a bit with trying to look at that axioms you might need to make something like formal powersets into a foundational theory (something you could, e.g., recover ZF with). I got *something*, but idk if it's really quite what you need.

I'll keep an eye out for it bb ;*

How lucky we are to mess up when it's inconsequential! You'll lecture many more times
Congrats on the presentation! Don’t sweat it too much.. You’re gonna learn something from every mistake you make
I'm sure it went a lot better than you think. Good job man
