excellent video helped me to understand a chapter of stewart book

The best teaching experience over the internet for the most difficult ideas to understand. No need to really spread because it's already a bushfire. Many thanks indeed & may you teach future generations forever and ever! Cannot express how grateful we all are?

Thanks for the feedback. Glad that the video did its job. Let every one know about MathFortress!

You are a pro at explaining! Thank you for putting so much effort into your work!

i already started spreading the word. PLEASE keep making these videos! seriously, i think a lot of us would appreciate that more than we can express through text :)

Incredible! Very informative and brilliantly explained. You are a huge help.
