Math videos from University of Texas math professor Lorenzo Sadun. The calculus videos mostly cover topics from integral and multivariable calculus, although there are a few from differential calculus, too. The linear algebra videos follow my book "Applied Linear Algebra: The Decoupling Principle" and are used for M346: Applied Linear Algebra at UT Austin.

why do the antiderivative formulas look like integration formulas ???
Sir I know it’s been 11 years but could you start making videos on calculus again
Out of curiosity... What method is the calculator using?
1:46 Why are you dividing the coefficients by factorials at this stage? 2:55 And again here, how are you even getting these fractional coefficients?
short and precise
In engineering (chemical) I use accumulation functions to generate a function which represents rate at which energy is flowing through a differential area. This is known as heat flux [=] W*m^-2 *s^-1. Instead, now I know why we DON'T express the integrand OR the differential volume in terms of the spatial variable (x (cartesian), r(spherical or cylindrical). It's because we're expressing a "running total" of heat flux (3:23), therefore we cannot use the spatial variable (x,r) in the integrand. rather we integrate up to the spatial variable (upper bound). I wish my professor was able to justify the mathmatical reasoning behind this like you do. It's more than just "using a dummy variable".
Best explanation I've ever heard!!! Thank you!
This help me a lot, thank you
Thanks!
This video finally made it click for me. Integration and differention cancel each other - so neatly explained.
That was fantastic. Thanks so much!
What i am about to say applies to 90 percent of people teaching MATHS ! This explanations are not good enough ! only 3 /10 students will understand you ! because there are alot of gaps in your explanations ...... YOU SHOULD COMMUNICATE BETTER and aim to make sure that 8/10 students understand you ! Dont be lazy and assume that people learning are interested or have prerequisite knowledge make the effort to explain and point out the GOTCHAS . Such as : THETA is a freaking GREEK variable that you are using to represent an angle PHI is another freaking GREEK variable that you are using to represent another angle so theta and phi are variables just like a , b and c You didnt explain what is COS , SINE and tangent what are those !. You didnt make it obvious that SINE THETA + COS THETA =1 aka hypotenuse = opposite/adjacent Further more even before teaching all the above you should have taught them ABOUT the circle ALL the parts of the circle Theres more to it than just radias , diameter and circumference . I AM FURIOUS MAD that maths teachers are so lazy and not communicating stuff without GAPS ........ thus only 3/10 students can fill in the GAPS and the REST depend on cramming formulas without knowing WTH and why they are doing this calculations !!!!!!!
Lorenzo, can you please post the link to the market penetration video you referenced? This quite good, very clear and concise. Thank you!
Great teaching 👍
Thanks
While I like your analogy of logs < powers < exponents, I recently failed a quiz using this. It turns out in fact that N^N is larger than N!
Sorry but the proper name for this is Fermat's lemma, thank you.
why your new videos are not coming for so long?
Very simple and well spoken explanation sir
Lorenzo Please do something about trig with constants.
thank you very much Lorenzo!!!
Youre a good man Lorenzo. Thanks for the help.
Thank you!!!!!
Great explanation, and great example with the distance function. Makes a lot more sense now, thank you!
this made it confusing for no reason
Thank you sir
That really nice explaining! ; but what if the function of the second example was not linear? And just a curve? Can you create two areas to sum or substrace them to find the integral?
Thanks for this video. Very well explained THANK YOU!!!
Wondorous!
Thank you very much for explanation. I had programmed it before but don't know why. Now I understand it more correctly
Thank you for saving my math grade :D
Very helpful
Thanks my Brother, nobody explains this such well as you did
Your explanation was excellent, thanks.
Nobody has commented but this makes so much more sense than how my professor explained it today
Thanks!
Anyone know how to plot x = 0 as an anonymous function?
thank you, this video was helpful.
The text appearing on the screen as you speak prevent the seeing if everything this you are typing
You can turn off the closed captioning. Just click on the "cc" button.
Excellent explanation. Thank you very much.
thank you.
simply genius. ty for sharing
thank you so much sir
Could you plz send us the Matlab code ?
Here's some code for finding sqrt(5) with an initial guess of 2 in 4 steps. You can adjust as needed for other problems: N=4; % The number of steps a=5; % The number we're taking the square root of x(j)=2; %The initial guess for j = 1: N x(j+1) = (x(j) + a/x(j))/2; end; x % Print out the array of successive guesses.
Understood on the second watch. Thank you very much!
thanks foe the help!!!!!
First thank you for this explanation it's really useful ! it's just that I don't understand how the 2 in the first row just became 4 (??)
first five videos from linear algebra playlist sums 1/3 semestar of linear algebra, very good job
Can't explain how useful it was!! If anybody want to learn eccentricity, I will suggest this video.
Thank you, great explanetion.
So cool
