In college I minored in math. I took every level they offered in algebra, trigonometry, calculus, and differential equations and made straight A's. I graduated in 1973 from Florida State University. Now I'm 74 and all the math I learned, except for the basics of algebra, has leaked out of my brain. It's true that if you don't use it, you lose it.

your playlist on sequences and series were spectacular, short, concise and to the point practically leaving no gaps in the explanation. Looking forward to using your calculus 3 videos and hopefully if you come out with it, the physics 2 videos.
notomatoesx - Thanks!! I’m so glad that I was able to help. I’ll at least have a physics 2 final review up by the end of summer, but I’m also planning on doing other physics 2 videos as well as a vector calculus series. If you have suggestions for videos in those subjects, definitely let me know! Also, since I assume you’re still in calc 2 right now, you’ll definitely want to see my calc 2 final review video! I’ll try to make another one with my new setup (it just looks nicer), but we’ll see!
I've always been shit at Math (advanced Algebra specifically), and I failed calc 1 twice, as I always knew the Calculus steps to solve the problem, but my algebra was bad. I at least got partial credit for showing that I knew the steps to solve the problem, in Calc 1. Eventually, I moved onto Calc 2, and it was a ridiculously new beast. I still understood the Calculus steps I needed to do to solve the problem (could explain in detail why we were doing what we were doing), but even though I would try to "grovel for points" (which my Physics prof taught me), I'd get awarded 0 points, because I did not get the correct answer. I ended up re-taking Calc 2 3x, failing all 3x, and giving up. Point being, if you're young and smart enough to be watching this video, make sure that you pay EXTRA attention in Algebra; Algebra is BY FAR the most important aspect of any advanced Math class. Edit: As an aside, I think it's bullshit to have Calc 2 as a requirement for stuff even like Geology (which is what I was going for), as even Engineer friends of mine have said they just punch input data into a computer... completely blocks people like me (98% in Cell/Molec Bio, 99 in Zoology, 96 in Botany, A's in both Ochem A and B), who are intelligent, love the Sciences, yet are bad at Math, from doing what they love in life.
I agree with your the education system needs to change and change quickly. I too know many engineers who took all these math courses and never even use them in their current career. But for now us stem majors have to take these courses and get through them 😞.good thing It will be worth it in the end once we are done with these math courses.
Polar coordinates are from physics, I’m taking physics 1 for scientists & engineers and the first thing we saw were vectors and they’re components were polar coordinates
I am an honours degree mathematician but I taught many years in primary school ie seven to eleven year olds . I taught top juniors Sine, Cosine by measuring using large cm squared paper to create a circle and using a millimetre ruler to measure the lengths to a reasonable accuracy. A concept can be made simple as in this case to measuring lines and creating basic angles using a protractor.
Marcos Tejerina - I’m glad I could help, and thanks for the suggestion! I wanted to try to fit it all in 20 minutes, but watching it back, I really regret not going into depth on each topic.

I took calc an and bc in high school, and I’m now taking applied calc 2 but it’s like all review. I want to learn something but don’t know where to look, your channel is a great resource
Thanks man. I loved math too much so i studied it alone in pandemic. And i was wondering how can i keep improving. Finally i found this after searching alot about calculus videos
I actually didn’t think series were that bad. There was a learning curve with them, but once I figured it out, it’s pretty easy. I prefer it over integrals because with integration it is so easy to make a mistake because of all the simplifications you have to do. The problems are longer even if they’re not necessarily harder.
Lol, that was me too. I did the best in calc 2, 2nd best in calc 3, and prolly the worst in calc 1. Probably because I took calc 1 in HS and I was surrounded by people who were bringing me down. I think we all know that feeling from hs though.
I think your vidoes are great. I was lost for the longest time until I realized what everyone calls Calc 3 is our Calc 2. So I was using the wrong tutorials

Consider the region R delimited by the curve y = C− x^2 and the x axis. Use integration to find the value of C > 0 so that the volume of the solid obtained by rotating R about the x axis is 64√2/15π Note: Plane sections known to the x axis are circles. Would you help me?
“How can something with infinite terms have a finite value?” Isn’t the whole idea of a derivative that you represent something finite value and dividing it up into infinity many terms?
I believe you are confusing derivatives with integrals. An integral will add up an infinite number of terms to possibly get a finite value in return. If you are still confused on this, let me know and I can explain it further. Continuing with this integral idea. Yes, an integral is very similar to an infinite series; extremely similar in fact. With an infinite series, you are still adding up an infinite number of terms to possibly receive a finite value back. A really intuitive example of how this can happen is with the repeating decimal 0.1111.... You can represent this as an infinite geometric series 0.1 + 0.01 + 0.01 + 0.001... An infinite number of terms adding to be a finite value. It’s cool stuff! Let me know if you have any questions. I hope this response helped.

You are moving on and not allowing your fellow students pause to take in what you are saying. Why not present this as you did in boxes but take a bit more time to show where they fit into the course. You seem to take for granted people have done this course and know what you are talking about. The comments that are positive seem to be from those looking back like you and already know what you are talking about. You just gloss over concepts like parametric equations without stopping long enough to explain WHY use them. Similarly partial fractions are just mentioned with not even a simple example of the idea. You could take a very simple fraction and just using A and B explain it. Yes it gets more complicated but the basic idea would make things clearer if you have not met it before,
