I think it’s cool when a math teacher is slightly eccentric. It really helps me stay focused and engaged for my studies.

[@TheMathSorcerer]

hmm, thanks lol:) glad it was helpful!

[@emilyphilpott1890]

YOUR TEACHING SKILLS !!!! >>>> Oh my word, I have never seen a college math professor explain ANYTHING on this level. It's beautiful. The way you wrote down y^6 = (u^(-1/5))^6 to help your student. The fact that you question yourself as you're doing it rather than answer condescendingly to questions. YOU. You, my friend, are a true sorcerer.

[@TheMathSorcerer]

❤️

[@TheBuddybro1]

You are easily one of the best teachers I have ever seen. You are enthusiastic and create an interactive learning environment with your students. It is great that we can hear the students questions and your explanations because many times I had similar questions. Thanks for your help and now I am going to ace my exam tomorrow

[@TheMathSorcerer]

Ace it! Good luck😄😄

[@Lucasinbrawl]

The atmosphere is so nice! Everybody wants to learn and questions are welcome...I'm more used to teachers making the students feel really dumb, not explaining stuff twice...or even once properly x) So nice class, really enjoyable

[@TheMathSorcerer]

Ya that was a good class!!

[@VndNvwYvvSvv]

Yeah, most math dept professors are stuck up, especially foreign ones. I think since they immigrated, they've taken everything much more seriously to be competitive, but it makes classes dry and more difficult to understand. Anyway, yes. It's nice when a professor can explain things in human terms rather than rigorous mathematical proofs.

[@garrisonrichmond2776]

Your explanation of Variation of Parameters was absolutely spectacular. It never made sense to me, even the second time taking the class, until I heard your explanation. I cannot express my thankfulness for this video - I have my final in 6 hours and I think you might’ve just helped me secure a solid final grade. I wish I’d discovered your channel much earlier - you definitely have a gift. Thanks again!!

[@TheMathSorcerer]

Thank you for the kind words! Good luck!!

[@danielimbriaco7135]

This professor actually explains diff eq, based on previous experience I didnt think that was possible.

[@TheMathSorcerer]

thanks man:)

[@luckybubble8012]

bruh this class is lit , the method he uses in learning and the energy ....

[@TheMathSorcerer]

👍

[@jacobharris5894]

I passed diff eq a long time ago but your lectures are a joy to watch. The excitement and passion for math bubbling up as your teaching is a beautiful thing.

[@shakefl]

Good luck everyone. Not in this class but I'm studying for the same exam!

[@TheMathSorcerer]

:)

[@dragosmanailoiu9544]

I got a 96 on my Differential Equations final this year, all thanks to you

[@TheMathSorcerer]

Awesome good work!!!

[@westinerwin4733]

This guys a mad man and I wish I was in his class.

[@fernandogarciacortez4911]

Man, what an excellent teacher you are! So involved, and it is outstanding how the class seems ~alive~. We need more like you.

[@TheMathSorcerer]

Thx man

[@onpoint2292]

I'm not part of your class, but this lecture sped up the review process for me. You were about as clear and concise as my own Diff. Eq. professor, but introduced me to slightly different ways to execute Differential equation solutions (the tabular method as opposed to by parts, for example). Keep up your teaching style. It is effective!

[@TheMathSorcerer]

happy it helped:)

[@niallspotat0e823]

i love that i actually dont get bored reviewing this and i can just follow along easily

[@jacobharris5894]

I know he’s probably the most enthusiastic math teacher I’ve ever seen.

[@Ben-pv9yh]

I love how excited the professor is. Thanks for this. I am starting a DefEq class next week and wanted some insight. I will definitely be coming back during the semester.

[@TheMathSorcerer]

Best of luck!

[@mustafamosavy4458]

Breaker down to peaces I study engineering in Germany in bachelor and it’s quite nice to watch quite different methods of explaining and teaching ❤thanks for the videos

[@cocotheloco3144]

came here to say that i passed my ED course thanks to you, amazing playlist

[@WeatherWorld]

I’m not even close to differential equations, only in Calc 2 rn, and your enthusiasm for mathematics and your high energy is super motivating and inspiring me to work on more math. Thankyou so much for all that you do! :)

[@D.pietertje]

15:14 you mentioned tabuylair or parts. I never heard of tabulair. But isnt tablair the exact same as parts but just more structuarly written down. It is the same essentially right?

[@djm6683]

it is time again to use this video! thank u Professor and good luck to everyone!

[@TheMathSorcerer]

You are welcome!!

[@Maggio97]

I love this, when a student asks “a stupid question”(profs favourite word) you go on and recap explaining why, and I wish we had more teachers/profs like you! I was lucky enough to have a few and it’s the reason why my grade is high ! Keep up being amazing !!🎉

[@MrSimmies]

There are no stupid questions. Only stupid people who ask questions!

[@pedropassos_]

My professor makes exams extremely hard for this class and this video clarified a lot! Thank you so much!!

[@TheMathSorcerer]

You are welcome! I am so happy this video was able to help someone 😃

[@SapereAude562]

The enthusiasm in explaining these awesome analytical human achievements should be a minimum pre-requisite for anyone teaching Math. Love you channel man, really happy to come across this great content (been growing my Math book collection thanks to you! ahah)

The Math Sorcerer Thank you! I'm planning on getting my Ph.D in Mathematics or Computer Science to start teaching at the college level.

[@TheMathSorcerer]

Very nice!!!

[@jacobharris5894]

The Math Sorcerer Yeah it is. We had a little sneak peak into differential equations in my calc 1 class though which was pretty cool. Some of the other students were upset because it wasn’t part of the curriculum with other professors and it was on a test and the final but I thought they were fun to solve.

[@Crashwave321]

Thank you. Not just for the excellent math, but for calming my nerves lol

I just had a differential equations exam and on the last question of the method of undetermined coefficients, I accidently wrote down the "particular solution" as my final answer instead of the "general solution". The pieces were there but I forgot to incorporate them together. This is what happens with me and exams!

5:40 shoot ohh okay, duh, solved Y for U that's where he comes from. 6:25 haha he got a bit confused as I did XD 7:40 Damn that's solid, forgot that exponent rule lol 8:40 haha student forgot same exponent rule I did :P 9:10 Oooooh shiiiit, lol Integrating factor, gonna need to review that section aswell 10:00 Dang I think that LA problem woulda been a juicy one to get ready for this steak-meat :-D 11:00 Good Question: about p and e. If it du/dx U sub is with respect to x, if it were du/d0 it would be with 0, or du/dt it would be with respect to t. Cool beans my dude! 14:00 Tabular, derivative of 5 is 0 14:35 Partial credit?

[@joshwoods7207]

I am currently in my first year of university in the UK (about to go into 2nd year) I wanted to ask about masters and PhDs as that is my big goal, I know it's a long way off but do you think that if you put the work in that anyone can do a masters or PhD? I always keep thinking to myself that when I struggle on simple things or I see a proof method which I would never have thought of which seems very obvious then it brings me down as most of my class understand it well. I have quite a short term memory, I understand things very quickly but also easily forget important details. I just want to think realistically about if the average person can get one. I did pass year 1 with a first class but trying not to get ahead of myself as that was the 'easy year'

[@TheMathSorcerer]

Well I would say continue pushing through it. If you can do well in the more advanced classes like advanced calc, abstract algebra, topology, etc then you got this.

[@joshwoods7207]

@@TheMathSorcerer okay thank you! I will keep at it for sure, do you have any advice on how to learn analysis efficiently? I start it next month, I have lots of books on it, but it's a lot to take in, just don't really know how to approach a lot of the proofs.
