Where is “hahaha” guy
What book is the class using?
great one
Honestly thank god for you. There's no way I'd be able to understand this by reading from a textbook.
I fear we have lost you sir. What a devastating loss. I hope you are well and I will always continue to look for your return. A long long time fan.
Anyone know what math text book they are using?
Back through this course a second time to review the material. Gotta say, I love how he gets you to really *see* what's happening geometrically rather than just plugging stuff into formulas.
Now I'm watching this at 1.75X speed and God this makes these videos way shorter!!
14:17
38:17 identity
If I ever found a woman that laugh the way that one student does to what ever the teacher says. I would consider myself lucky.
From watching pre algebra to finishing calculus 2 now starting calc 3 just entered my 2nd year Electrical Engineering thanks professor from Australia …..Ps if ur ever in down under I’ll shout you a beer or 2 cheers
Just watched the entire lectures in a few days, this is amazing to get a good understanding of the basics.
where is lecture 14.5?
He is my favorite teacher ❤
COME BACK I NEED U BRO
Hello Professor Leonard, seeing your deep passion for mathematics is a great inspiration to me! I would like to say that you are one of the best mathematics teachers I have ever seen in my life. It is a great pleasure to listen to your lessons, thank you for everything!!!💙🤗
Wishing you all the best Professor. You are the only reason that I actually understand calculus. Massive thank you!!!!
Hey professor, about time for another annual "I'M Back" video before you disappear for another year? Please don't even think of quitting CZcams for any reason. Please.
his profile is so acurate, he is superhero for us, thank you very much for everything, every content you uploaded
41:10 why cant you just integrate both sides?
Where have teachers like you disappeared?
video so good, I HAD to leave a comment. Thank you Professor. You are my superman.

Sir pls upload Linear differential equations: - Operator D - Rules for finding the complementary function - Inverse Operator - Methods for finding the particular integral - Working Procedure to solve the equation - Two other methods of finding P.I. - Equations reducible to Linear equations with constant coefficients - Linear dependence of solution
anybody know what book he refers to?
I am struggling with math so much It’s pushed my graduation date back. I am an accounting major, but I have to pass pre-calculus after a few years hiatus. It’s my second time taking the class and I have to get a B+ or else I get dropped from the program at my school. I’ll be using your course to hopefully understand more.
Take care professor, We love you
00:00 Calculus review: Section 0.1 - Lines and Slopes 06:29 Learn how to find the equation of a line using fixed points and slope formula. 12:39 Learned how to graph a line using slope-intercept form 18:24 Learned about graphing lines and slope-intercept form 24:29 Finding equations of parallel and perpendicular lines 31:56 Angle of inclination and slope are related through tangent. 38:08 Finding slopes and angles using trigonometry 43:34 Trigonometry is important for success in calculus.
56:29 amazing the word joke hahah
.
He is the most calmest teacher i've ever seen
What book do they use?
The last thing about the Pascal Triangle is honestly mind boggling!
Just came to say I got 100/100 in my calculus 2 final exams and 90 cumulative for the semester thank you so much 🙏
Did anyone ever figure out his math to get time as a positive @ 50:39
Nvm just keep watching, he’ll catch the step errors
You Sir are HEAVEN SENT! GOD BLESS YOU!
Me too!
I love when he says, "I'm gonna go fast and not explain it all" then proceeds to give a fairly thorough explanation 🤣 much preferred to the other way around!
What a legend. Salute to u Prof. Literal blessing for all of us studying multivariable calculus all over the globe.
Thanks sir!! Your video makes me sleepy~
Great lecture as always! I just wanted to mention that I think it is a mistake to say that f(x)>=g(x) is sufficient for convergence of f(x) to imply convergence of g(x). As one of the students asked, it is possible that g(x) is not bounded below while f(x) is, so f(x) could converge while g(x) could diverge towards negative infinity. For example, consider f(x) = 1/x^2 and g(x) = -x^2 and the interval from 1 to infinity. Clearly, f(x)>=g(x) in this interval. However, g(x) is not convergent even though f(x) is. Hope this helps other viewers who may have gotten a little confused about this.
Its easier for me to say its intuitive to do these things than to explain them
Thanks Leonard you're the best!
Imagine an alternate universe where he never posted these lectures to CZcams! Seriously, thanks prof <3
Daemon targeryon teaches mathematics 😼😄
Thanks Professor Leonard! Your example of the tension in the ropes holding a weight will definitely help me in my last ever high school exam! Thanks so much!
love u superman from sri lanka

Hold up why can’t I have Clark Kent as my algebra teacher?
why is depth of box x?
