Nicely presented! Are you a student right now? In tw or in the US?
Actually, I'm a math teacher, private tutor, and one-time teaching assistant. I live in Taiwan
Dave's Math Videos ah I see! Weird that I didn’t get a notification but luckily I came back to check. 你的英文超好,然後我看到你在台大附近走路的影片所以我覺得你是學生.不好意思我猜錯了.很高興認識你也謝謝你看我的影片
@@blackpenredpen 哈哈，事實上，我之所以英文還不錯，是因為我在美國長大，二十多歲以後才回台讀研究所。目前在台大附近工作。
Dave's Math Videos 喔喔喔！超棒！ 不好意思現在才回 notification都沒來剛剛也看到你的留言了，謝謝！ 也祝你的頻道好運！
i guess Im quite off topic but does anybody know a good website to watch newly released series online ?
Are you John Wallis?!!Because it seems John Wallis made this video and explain it !It was just great. Thank you so much
Thanks for your comment. I'm not John Wallis, but I though his proof was very interesting.
Hi, just subscribed! I like the introduction of the mathematician, and the overall solution. Remember I was here before 25 subs!
Thanks! I hope I can keep on producing content in the future
Why is it (2n-1)(2n-3)... rather than (n-1)(n-3) If we look at I4, it would get computed as (pi/2)(7/4)(5/2) with this sequence
Dude, your videos are top quality :D Please get a good quality mic, you will observe a huge change!
Thanks. I'll get one soon but lately I've been busy with trying to move to a new apartment.
Sir I think that double factorial expression of odd values of n is wrong

Great video man!!!
Thank you!
so helpful, thank you!!
You're welcome
Just use cos^2 = 1-sin^2 during integration by parts then you would save a lot of steps
Nice videos! You gained a new subscriber! 我也可以说中文！我十二岁了，和我很喜欢学难的数学！我是美国人所以我的中文可能是不太好，对不起！P.S。我也有一个数学的TH-cam 网站。
The Theoretical Nerd - Learn Math Science, Etc. 你超厲害！ 你學中文多久了？ btw, I subbed to ur channel.
谢谢你！我已经学习了七年，从幼儿园就开始了！P.S. : 我真的很喜欢你的TH-cam ;)
The Theoretical Nerd - Learn Math Science, Etc. 你超棒！
谢谢你！！：D
