Yeah sadly this is so true, so many people feel and choose to end their life because they are struggling in college and begin feeling hopeless. If more professors made an effort to not let students fall into the margins and instead taught methodically, checking if the class is following, in a style similar to Professor Leonard, many of those students would have alot more hope.
I grilled the internet and all the online courses from the high class universities to refresh my memory with calculus to get myself ready for Msc finance & Accounting at lSE, I didn't find one like yours. No words could describe my appreciation for ur explanation. Nobel Prize should be awarded for people like you. On day, I will meet you, hopefully I can pay you back :)
At the moment, I'm a graduate student but I never understood calculus during my undergrad. A few weeks ago I was telling a friend in grad school that I needed to enroll for undergrad calculus and he recommended that I follow professor Leonard's lessons on youtube. I started watching from lesson 0.1 and I feel like professor Leonard just empowered me. Thank you so much prof, you just made my life easier and because of you I am well equipped to understand and relate better to both science and math.
When I'm lost in a Calculus problem I just come to your videos and all is well. Thank you for all the time and effort you put into these videos. Your school and students are fortunate to have you as a professor.
Man I wish I had a teacher like professor Leonard in high school. I barely passed algebra 1 and failed every other math class. I’m currently going back to school after the army and have worked my way up to calc from elementary math over the past year. Needless to say professor Leonard is a huge help
@@issahmusenga1196hey I’m currently struggling with calculus because my algebra wasn’t good I came from Mexico to the us and I only study my senior year of high school so i feel behind or not enough any recommendations?
Professor Leonard I want to say thank you for posting these videos on TH-cam. I am going to study in university after 3 months and these precise definitions of calculus that you have provided is a gift for me. Now I can go confidently towards my future... Thank you
I have found your lectures on youtube and since I am an electrical engineer major at USF, I have found your lectures on here more beneficial than the ones I sit in on a daily basis. I wanted to thank you for posting your lectures. I just wish you actually were a professor at USF so I could benefit more from an actual sit-in lecture
I am in the same boat! A software engineering major and unfortunately my profs are pretty bad. They are not clear and concise and my calc prof has terrible handwriting which I can never read. I pretty much only go to class to know what kind of questions he puts emphasis on for tests, I usually have to spend a few hours teaching myself everything. Thankful to people like professor Leonard.
Not to sound condescending, but how did you even get into EEng without knowing this stuff? I did my B.Eng in mechatronics and then M.Eng in electrical (research was in the field of photonics). I would of been crucified if I wasn't extremely proficient in at least calc 1 in my first year, it was all assumed knowledge from day 1.
Well personally for me, I did very well in this stuff in high school but I had a large gap between graduating and college and I definitely did not do any math during those 4 years (woops). Lol so thankfully it is all coming back to me through watching these videos. The only really new concepts I have to learn are incorporating log, ln and the trig functions into differentiation.
Experiences in life vary. Not all universities are ran like a chop shop. Additionally, leading with "Not to sound (anything)" only amplifies that (anything) you are trying to avoid.
The absolute best calculus professor I have ever seen! I wanted a summer refresher with Calculus 1 from AP Calc in high school before I continue with my calculus classes... I DID NOT KNOW HOW MANY CONCEPTS I DID NOT ACTUALLY UNDERSTAND THE MEANING OF WHAT I WAS DOING. Professor Leonard makes you understand why you're doing what you're doing. I will use his videos even while I'm taking calculus the next two semesters.
This guy makes calculus look so easy. When I took calculus1 7 years ago, the professor never mentioned calculus is for solving slopes on a curve or finding the area between 2 points in a curve. He was more concern about making us recreate all the formulas we used in class from scratch.
For once in my life I honestly feel like I understand math. It's been years since I've been comfortable working out problems with numbers and somehow I feel like using these videos to prepare myself for my calculus courses has changed my perspective of why math is essential. Thank you Professor Leonard!!!
Because the power rule isn't introduced till later chapters and some teachers won't let you use it till you've learned the def. of the derivative function
Thank you sir! I got lost a little when my professor started to explain derivatives. After watching your video a few times, I felt very comfortable. I went to class today and was not lost at all, I followed EVERYTHING. Thanks again. You are definitely, THE MAN!
This might be my first time commenting on any video but I just have only one thing to say. WOW. You, Professor Leonard, are an ABSOLUTE LEGEND. I hope I can meet you someday and repay you, thank you, from the bottom of my heart!
It's 2023 and Mr. Leonard's videos are still the best. I love the easy and understandable language, which he uses. Also, I'm really interested in derivative of his biceps.
Twelve years later and your videos are being used by colleges to teach students, like myself, Calculus. Whenever the coursework uses one of your videos I let out a sigh of relief. Because I know that by the end of it, I'll actually understand the material because you go at a perfect pace when teaching and show all your steps. I'm never left questioning how you got from point a to point b. Also, my notes remain neat. I've had issues in other videos of making a full page of notes, only to have the instructor circle back to an earlier note section and add more information. So thank you from the bottom of my heart for making it not only possible, but easy, for folk like myself to learn.
Hello Professor Leonard, I'm one of the luckiest people around here who found your videos, your style of teaching is excellent, the way you teach can make even a donkey sit in the class quietly for 1 hour, you really teach the subject in a detailed manner, you do make the subject more interesting and fun, I opened my textbook and wanted to study about calculus but the way its explained there,it is impossible to be understood by me, but thank god i saw your videos, now I'm pretty confident that at least i have a basic idea of what's happening. Thanks a ton professor, your a blessing to mankind, I wish every student in this world can get a teacher like you, Once again thank you for taking so much trouble in uploading the video and making it available to the public for free, I'm from India and will never forget you in my life, if possible I would like to maintain contacts with you via Facebook in case i have any Doubts. Thank you Professor.
Thank you for posting these videos! I can finally grasp the concepts of the derivative with your examples and explanations. You're a teacher who actually teaches! Thank you!
Going back to school after a long hiatus and your videos are amazing. I've forgotten so much of what I've learned previously and you go into the perfect level of detail. Thank you soo much for what you do.
My Cacl professor is extremely difficult and gives no partial credit. It's either all or none (engineering school) . These lectures have become so helpful!
He's the kind of a teacher that every student deserves . He makes the subject less scary and make you fall in love with it. That's what a teacher should be like.
I swear by my god , you are going to the heavens directly without any questions ❤. You saved me and saved all of the student. You enlighten us God bless you professor Leonard
I'm re watching these videos after watching this series, Calc II, and Calc III while taking notes. You pick up on a lot of information better on the second go to the point where I can visualize a lot of what he's saying beyond what he is drawing on the board.
Every time I watch one of your videos, I feel like something clicks....even if it is a concept i THOUGHT I previously understood. Thank you so much!!! :)
I'm a freshman at ucsd and this is my first time having a calculus class ever. felt super dumb in my calc 1 but watching Professor Leonard videos have helped me a lot to truly understand the concepts and know why they formed. I'm currently watching the lectures up to where I currently am in class and I hope to learn a lot more and get good grades on my math class! I'm actually having fun while learning math, that rocks! :D
PROF I am watching your lecture from Kenya ... You are inspirational to me... calculus is becoming easy easier and easiest through you... keep up the spirit you are so helpful to all students world wide like me.... I wish you many years to come to help many
Good clear explanation, my calculas was a bit foggy when I lfirst learnt it 40 odd years ago but this Professor is shining more light on the subject, filling in the gaps of my knowledge, thank you sir.
We had our calculus midterm this week and I killed the limit thanks to you L-King! Now I'm rolling with you on the Derivative and will on Integral, when I see them questions I easily fended 'em off with the things you taught, limit has ended, lol
He really seems to genuinely care about his students level of understanding. Even though it results in more skipping ahead for me, it's refreshing to see a professor that hasn't lost the will to teach.
idk if this is a good strategy but basically my teacher just reads off of the textbook (yes even in an online class) and since I don't understand anything, I make notes of the textbook as I go along and then when my exam is near, I BINGE WATCH the lectures I need. but frl these videos are not only informative they're also fun cuz it's in a classroom setting and prof leonard is dynamic in his way of teaching so watching these 1-2 hour videos don't even feel like a chore. I actually FEEL like i'm learning.
Thank youuuu I get excited when I pause the video, solve the problem before you do it and then I see that I got it right :) I am good to go for my exam
Love your videos, it's helping me get back into calculus after a major life event that forced me to drop out of college. Love the jokes and humor as well. I just wanted to point out a fun fact lol. You said "differentiability" was a great Scrabble word. Well really it's not because no word longer than 15 letters can ever be played in a game of Scrabble when following the rules 😆
I felt the need to post this comment. I stopped doing work for calc during week 2 of college. I'm now at week 7 and am cramming as hard as I can to save the course. You have been beyond a life saver. P.S. Don't do this. Just do the work from the start lol
Jim Midgley are you still alive ?? Not being funny but wow 1951 ?? You must have been born in the early 30s . You’re almost to the point of being in the “greatest gen “ I think
1:03:32, I can see positive infinity from the left but not the negative infinity from the right. I'm trying to cross reference the visual with the derivative function or even just the slope one and I don't see it. I think this has to do with where you choose your (x1,y1) point and the (x2,y2) point. I always choose the 2nd point to be more to the right.
Doubt you will see this Professor, but I wish you had a pdf of practice problems for every section! Or at least problem numbers for every section from a recommended book! Love this and reviewing calc 1 to calc 2 to prep for calc 3. Hoping to finish up to calculus 3 by summer so I can be ready.
ive always loved math and im even a math major however, when i took calc 1 for the first time i hated it... the professor didnt teach well and her exams were 10x harder than the examples on her study guide and on her quizzes. im taking it again and my new prof also sucks at teaching and has even admitted that he didnt like his job... im almost thinking of changing majors but if anyone can convince me to stick it through and actually learn this stuff it'll be u Superman
***** I wish! I passed Calculus 1 and now im taking Calculus 2 but my professor has a very heavy accent and is hard to understand but thankfully Professor Leonard has Calc 2 videos too :)

+Miguel Merino Before I take AP Cal I believe I fall in love with math as well... But now that's just a midnight...
***** I wish! I passed Calculus 1 and now im taking Calculus 2 but my professor has a very heavy accent and is hard to understand but thankfully Professor Leonard has Calc 2 videos too :)
+Sveva Ramasco hahahha adesso sto studiando per il mio esame di Calculo, veramente i professori fanno schifo, tutto lo ho imparato da qua
your'e an angel for us :) keep it up with the good math! GOD bless you!
I just wanna say thanks for this great work! You're amazing!
