I rushed through this one. Not sure why the first 30 seconds are blurry. The video begins with a series of 10-second graphs. If you want some practice with those techniques, videos that will give you some are on the channel. You might have to spend a few minutes looking. I've attached a paper I wrote many years ago that explains the numerical processes. The video ends with a few numerical exerc...

Please post all your videos organized in playlists in the correct order we need to follow them so everything makes sense as a learner.
I will try to do that at some point. I started uploading videos for my classes during covid. My facility with this platform is limited, but I will seek some help soon. Thanks for the push.
Yes for -3, and no for old, for you "traced it pretty darn well."
appreciated
You are amazing Sir
Thank you for the kind words.
... Pondering. 🤔
ua-cam.com/video/HM28n1K9H_4/v-deo.html In my humble opinion, 6 x 1.0001 = 6.0006
Thanks for catching that.
Thank you for the background.
Most welcome.
To the point.
I watched it twice, but, the second time with a pencil and paper. Thank you for jogging my memory after a hiatus of 53 years.
Thanks teacher ✨
Most welcome. Best of luck with your studies.
👍🏻👍🏻👍🏻
Thank you for your explanation
Most welcome.
Very good maths for experimental Physics
I do quantum research and live on $5 USD a day
All profs need a personal trainer and a new haircut!! Do you guys all go yo the same industrial style 1936 Berlin barber? And for the love of the universe!! What's with hunchbacks, double chins, and flat a$$es all over the place? An important concepts eludes ALL scholars, THE BODY ISN'T THE BRAIN'S WHEELBARROW! Physical health helps the brain.
I appreciate the advice.
I didn't even reach this level in math but this guy looks like an absolutely amazing and sweet teacher. Keep going !
Very kind of you.
Hello, congratulations on the content, very good and informative, keep going buddy, you were the best study asmr I've ever seen, haha, even, Olá do brasil! Sim, você chegou ao brasil, atingiu nosso público e nos iluminou com seus ensinamentos. Continue firme e FORTE!
Thanks for your kind comment.
We need you in Usa Boarding schools
Thank you for the kind comment.
Very good presentation!
awesome video sir
Enjoy your studies.
I’ve always had appreciation for those in mathematics. Im a senior studying chemistry and when taking my math courses the confidence behind the work is astounding. I wish my chem professors had that haha everything they say seems to be a question
Thanks for chiming in and good luck with your studies.
Good Job
The video taught me a lot in only 16 mins, thanks!
I'm glad you got something from it. Good luck with your studies.
teacher, gotta thank you for the vids realy been opening my mind these days seen 6 of then and counting up. Thank you
Glad you found them interesting. Good luck with your studies.
maths is always so interesting
👌
Really enjoyed your lecture, but one suggestion please use a good microphone, so that your voice will be clearer and users will be beneficial
Thanks for the feedback. 5 years ago I was still using a flip phone, but maybe an old guy can still learn a few new tricks.
Man, enough with old white dudes dominating STEM by cheating and pushing everyone else out.
Brilliantly connecting the dots in high school maths. Thoroughly engaging and enjoyable presentation. No gimmicks -- just pure knowledge with a touch of good humor. Much, much appreciated! Let's hope the algorithm continues doing its job by spreading this great lecture further. 😃
Very kind of you.
Being shown how the theory is actually applied helps a great deal. It is equivalent to assembling a jigsaw puzzle and recognizing where a piece fits without expecting the puzzle to be finished all at once.
the art of pedagogy in what is missing in all of the education throughout the world. thank you being a pedagogic master and give a deeper understanding to subjects that sadly are being taken for granted and not explored.
Very kind. TY
Hello Professor ,I certainly need to rewatch this video again to grasp almost everything ,but this I know , that maybe I was able to understand how you were connecting everything together ,and for which I am very grateful. Also ,the way you were moving around the room and showing us the boards really made me smile. Thank you for keeping my love for math alive.
Thank you for the kind words and stick with it.

Just here to Drop a like and say thank you. Keep up the great work! I’m not a student, just a happy viewer
I appreciate that!
One idea I had was to describe these by the color spectrum, such as to visualize the logarithmic and exponential functions by fixing a color like white X and black Y so when White is 0 the function is fixed at the Y axis for Black, and every color greater than 0 gets darker and every color less than 0 gets whiter, so blue has two shades one darker and one lighter, grey is closer to the Origin, is this a proper way to visualize logarithmic scales?
I guess you'll have to play with it. I'm a big fan of looking at problems from different perspectives.
If you do create that model, I'd love to see it.
Thank you Jim as a third year math major it’s a good hobby to sit and watch you develop the mathematics
Thanks for the comment and good luck with your studies.
Hard to hear correctly with all the echo in the room
Thanks. I'll open a door or try a different room next time.
Well presented. Math never was my thing but I will view more if you can keep it simple.
Thank you!
You're welcome!
perfect thanks prof Jim Vollinger <3
Most welcome.
A very interesting approach for a theme that sudents are normally afraid of: FUNCTIONS
Thank you for your commentary.
Nice 👍
nice
hello Big Senior
Interesting Approach
Glad you took an interest and thanks for saying hi.
very useful!
Glad it might help and thanks for saying hi.
Loved the video I was learning about graphs from the book Play with graphs by amit m agarwal. You can surely check it out too
Thanks for sharing and great uni! I'll check it out.
Great content and message! Practice problems seem like musical scales in that an understanding of their relations with one and other allow for the exploration of compositions, let alone the ability to compose for one's self, analogous to building a model for a unique problem. Physics has been fun lately for practicing applying a diverse set of skills in approaching the construction of agreeing models from different points of view.
A rather interesting perspective. Thanks for sharing.
Hiiii
Hi back.
@@jimvollinger589 I am Eugene by the way from Ghana. I must say I am impressed by your passion for math till this age. I completed high school last two years and planning on pursuing math as undergrad. I have since then been solving problems and working on proofs 🤝. I wish you could guide or even advise me on how to navigate this path I would want to take❤️
I'm afraid I just saw your post. If you are pursuing a math degree, I would encourage you to browse the topics before you formally study them in class. I'm not a fan of sequential learning. I don't think it serves students well. Many concepts in math simply take time to grasp. The more times you get to ponder the topics the better you will probably do. Just my opinion. mBest of luck.
@@jimvollinger589 thank you very much Sir
