I have been running away from Math for over 50 years. Thank you so very much for opening up this world for me. Somehow, it makes me feel more connected to something bigger than myself.

I really appreciate you doing this. It's helping me build my confidence. Im very visual and you've done that for me

Sir, I m from India ,I am a house wife, I learned calculus 20 yes ago, now I have forgotten many of those, thanks for yr help.

You're the best math teacher anybody can ask for. Thank you.

I appreciate how you simplify things.  In my opinion every other math tutor is just rushing through the syllabus. You are actually teaching, keep it up.  Thank you 👍

I'm 39 yrs old, never took calculus and going back to school .. you have helped me build my confidence thank you so much!!

Thursday. Raining outside. Watching this at 08.15 am. I forgot I'm 39 years old for a while.

Where can get the DVD

i be messin with Java on and off and i came across a book
called Physics for Game Programmers and it stresses derivatives
didn't understand when the book explained it, but i understand
much better with this video presentation

for the first time in my life , its not, ooohh I get it it ,its ooooh shiiiit this actually makes sense. 😭😭😭😭😤😤

Thank you very much. Sir, You are expert at simplifying difficult subjects in an incredible way.

I love your videos; they express the concepts very easily and it is perfect for a person who is beginning along side someone who is in need of clarifications.

I am in high school now preparing for AP Physics 1 and I know i need to have basic concepts of calculus, so I found these videos and they are so clear. I love math and physics, so I've been watching physics videos non-stop alongside math videos and I came over this one in my suggestions.

Thank you for these videos!

nice very nice explaination.

Great explanation 😀😀👍

Greatest of them all...gratitude dear Professor 🙏🙏

Finally things are starting to make sense to me. Thank you.

Thanks much for going into details and making it easier to understand.

Wonderful lessons, how I can buy DVD?

Sir, your videos are fantastic. You clear all the basic concepts about Physics and Mathematics. We students always need great teachers like you Sir. Dear Sir, can you please give all of your lectures free of cost like Khan Academy is doing? Because most of the students can't afford to pay you, so they can't get your best education videos.

Thank you so much for your explanations, they are amazing!!
