What is the feyrman's method? Curious. If I'm using any method for anything that would be interesting that would be surprising, ha. I suspect that anything I'm reporting on has likely already been done, I am not an active researcher only reporting on fun things from 20 years of teaching to share with my students and family. So this channel is really only a release for me, a chance to do something other than worry about grades and teaching (I teach 1200+ students a year and don't get to do research). So any method that I overlap with is purely by accident.

@ emm, Isa method that we use when nothing of calc. 2 methods works Feyrman born May 11, 1918, New York, New York, U.S.-died February 15, 1988 Os Angles California) is an old method btw

And thanks for teaching maths, people needs people like you (Bc most people think that this is extremely difficult) , but I don’t think so

you mean Feynman as in Richard Feynman, one of the greatest physicists of the 20th century

Lovely, the start of Taylor series (error bounds) in Math 126 is a bit dry, but things pick up by the end. Unfortunately you don't get to do very many examples that I would call "fun", but I hope by making a few videos like this it will make it easier for you to enjoy that part of Math 126.

Thanks for the suggestion. Does this video scratch that itch for you: kzbin.info/www/bejne/Y4TXanpvr8uhnrc

Thank goodness, I'm glad you still get to enjoy donuts, ha.

Thanks for your question. I could talk about Euler and his formula for many, many hours, don't tempt me, ha. After you take Math 126 and learn about Taylor series, come back and I can derive Euler's formula for you. I think you mostly would encounter these ideas in a course in complex analysis which requires you to stick around math for a while. But maybe check out the book I mention. Thanks for watching.

Lovely, I should note I may be slow to make these videos, but I will add this to my list, might be a while before I get to it (I'm grading finals and have a long, long, long list of other goofy videos in mind), but I'll add this to my queue. Thanks.

Lovely, my department may ask me to teach Math 126 this summer due to a budget issue and they want me to get enrollment as high as possible, so you can help me by advertising Math 126 in the summer, I need at least 100 students, but more would be better. In other news check out my weird math videos as I'm having fun on those. Good luck on your final.

Yes, it should! Two mistakes in one video, darn it. Sorry, I'll need to remake this in the future, and thanks for pointing out the error.

Haha, me no subtract good, thanks for pointing that out. I am not doing as careful checking in order to get these out quickly, so I really appreciate errors being pointed out in the comments and I'll polish these videos up in the future.

What is funny is that my final answer is still correct as I made another subtraction error in the next step to fix my error. Two wrongs did make a right, hurrah.

Good suggestion, my family has played that one (a bit more Catan Junior as opposed to Catan). But they key is to find an interest, or weird, or funny math question to ask related to the game, have any ideas?

​@@Dr.LovelessTeachesMath Well I spoke with some friends, and one of the things they mentioned was winning the game by gaining victory points from methods outside of building settlements and cities. Usually my friends do this by collecting development cards and hoarding them until the very end where they suddenly reveal they have a couple extra victory points that allows them the game. They also do this by attempting to build the longest road or acquire the largest army for bonus victory points. I guess my question is, aside from building settlements and cities, what is the best/fastest alternative way to gain victory points? Maybe it's not the best question to ask because Catan is just a bunch of probabilities and it would vary a lot depending how many resources you are able to take in but it could be interesting. Thank you!

Repeating what I said to someone else below... I will add this to my list, might be a while before I get to it (I'm grading finals and have a long, long, long list of other goofy videos in mind), but I'll add this to my queue. And I'll find a quirky, funny, or odd way to ask a question that likely won't help you, but will make me laugh, which is what matters to me, ha.

How about this: kzbin.info/www/bejne/jGm9p2WhZ6qhfJYsi=E3jDZgpfYIfusRpV

You can do it! Where are you stuck, let me know on the discussion board, I believe in you.

@@Dr.LovelessTeachesMath I WATCHED A LOT OF YOUR REVIEW VIDEOS AND I AM FEELING A LOT BETTER, I will not be scared to use the ed though if i need more help!

Thanks for watching. This is all for fun. I like to think about someone trying to shuffle 1000 decks, ha. There are sometimes ways to extract a coefficient of a polynomial or power series without fully expanding, I didn't think on that as I was able to expand in this case. With 1000 decks, I'd have to think on it more. How did you find my video? I am mostly posting for fun for family and friends. Surprised anyone else would watch (and stay awake), ha.

@@AndyLoveless-jj3cr I'm a big fan of cribbage and maths so somehow youtube knew to suggest your video to me. I thought the counting problem you were tackling was fun and I enjoyed following your progress in the mini-series. To solve 1000 decks, you can work over a quotient ring Q[x]/(x^16), which is a lot faster since it's just a 15-dimensional Q-algebra.

Yes, thanks for pointing that out, I didn't check my work, boo on me. My first term on my final answer of the last example is off by a factor of 3, sorry all. My correctly written solutions can be found in my exam solution here (problem 2(a)): sites.math.washington.edu/~aloveles/Math125Materials/w15m125e2solns.pdf

Ha, good point. I made this particular entire video without the answers first... but I forgot to hit "record screen"... because I am an idiot. So then I redid the entire video again (which is painful to re-recorded the exact same thing again), but I was too lazy to erase the answers I had already written. I am prone to small typos. But I am not worried about getting 100% on these tests, I was never good at things like that. But I hope videos like this help you with how to approach exams. Hope these are helping.

@@Dr.LovelessTeachesMath vid is still helpful i am just wondering how long it would take a math prof to do

This is certainly not true, but thanks anyway. Hope the videos are helping.

Thanks for the input. Trig plays a bit role later in Math 125 (sections 7.2 and 7.3). I'll review trig when we get there (and maybe make a few supplemental videos as well).
