Welcome to my channel. In this channel, I post videos for my online classes and videos to help my students with typical questions in their math classes. In the near future, I will be focusing almost solely on Calculus material, as that's the next class I will teach online.
Finding a Basis for the Null Space of a Matrix
In this example, I show you how to compute the basis for the null space of a matrix directly from its reduce row echelon form without rewriting the equations.

Nicely explained
Thank you for watching! I appreciate your comments.
You are an excellent teacher thank you very much.
Thank you so much!
Nice
Thank you so much! I am glad you liked it!
Great video. Nice presentation. I think these are going to be very popular.
Thank you so much! I am glad you enjoyed it. I will continue to create videos for the whole calculus sequence. Hopefully, they are helpful!
Beautiful work!
Thank you so much! I will start recording in the studio again next week!
Looks like a bit of partial fraction decomposition?
Indeed. It is. Thank you for your comment!
Please note that at the minute 10 mark, I say copy my 9/4, but it should have been 4/9. That's a mistake. My apologies!
Please re arrange the order so can follow
Thank you for your comment. What order would you consider would be more conducive to understanding? Thanks!
Today I learned that division by zero is not possible unless you are Chuck Norris.
LOL! Well, you were paying attention.
This video made me clean my monitor
I had not noticed the glare. This comment is hilarious! Thanks for the comment.
Thanks Dr. Franco
You're very welcome!
Great vid. Keep it coming
Thank you so much! I took a break over the holidays. But I am getting back to it this week.
is this dude writing everything backwards??
No, unfortunately, I'm not that skilled. The video is reflected post-production. Thank you for your comment!
oh my god. You practiced inverse writing for viewers! that's awesome.
I'm sorry to disappoint, but the video is reflected. Thank you for watching!
🎉🎉🎉
Best calculus teacher ever!
Thank you so much!
Explains it way better than my teacher so you're on track to 1m subs
Thank you so much! Glad to help!
im your 100th subscriber 😄
Nice!! Thank you so much! I am going to be posting on a regular schedule now, so I hope you enjoy the content.
Really great work. Thank you for taking the effort and putting these out.
Thank you so much! I am glad that you found it helpful!
underrated af
Thank you so much!
wow，you can write mirror words
I'm sorry to disappoint, but the video is reflected post-production. Thank you for watching!
Dude, this is some amazing content! Btw are you right handed?
Thank you so much! Yes, the lightboard reflects the image. So, it looks like I'm left-handed.
Excellent, thank you!
THANK YOU ANGEL
Hello there.
This guy should teach calculus at university
Wonderful! Thank you!
Awesome! Thank you professor
Thanks for uploading this professor! Very helpful before the test
Hey there, thanks a lot for you explanations! It helped me a lot in my mathematical methods for economics class. I would like to know at the end how X_0 and Y_0 disappeared? Because at the begining A^(i) should be multiplied by (x_0 ; y_0) vector. Did I miss smth?
the second to last problem... what happened to the 1/2? the positive and the negative 1/ cancelled but what about the 1/2 that was attached to the h^2? I don't understand how we just changed that to a h^2 (h squared). I am a student in your class btw this is just a family members log in my name is Markia.
Apparently I forgot that 1/2. You are taking the limit as h->0, so I did not notice it in the final answer. My bad!
thanks
Would please explain me what you did at 1:00? I quite don't understand
Super blurry
+Rex Rit Put it on HD, then you can see it.
Thank you for your comment. I tried it on my phone and got to see how blurry it is. As +MrBigbluejet if you put it in HD, it helps. I will make the font larger from now on and use Camtasia.
