Calculus - The product rule for derivatives

[Fernwald]

This program (and the associated comments below) clearly demonstrate that most people have problems with math due to bad teaching. Here the presentation is clean, orderly, divided into just the right "chunks" and, to top it off, delivered in a pleasing voice. Great job!

How can I spend 3-4 hours in lectures and be clueless, then turn around and spend 1 hour on this channel and know everything I didn't understand in the lectures?? Sometimes I feel like I'm wasting my money and that these channels should profit.

i literally pay a thousand dollars to my university and still not understand a thing... but i do get it in a 10 minute video?? you sir are the best, you helped me a lot!

This video was extremely helpful, thanks! I have an exam tomorrow and I feel a lot more confident about it now

You make everything so easy to understand. I am going into my first calculus course and thought I would be struggling a ton, but if I just make sure to come and learn stuff from your vids while studying everything seems like it will be a breeze.

So clearly explained. No fuss, just, this is how you do it. Thank you for saying it clearly. I have no doubt that in the future we shall come to understand what finding a derivative means in the real world and why it is used but I shall be prepared for that when the time comes. Again a big thank you.

This guy is really good in explaining. I now believe I can manage to pass my calculus test. Thanks much.

Thank you so much! I have my first calculus exam this upcoming Wednesday and you made it so simple!

Thanks to your videos I could finally understand 18 hours worth of lectures. My only problem is that I get flustered when I see square roots and fractions. Help me overcome this hahahaha thank you again!

Thanks. Really helpful for 6th graders like me who can actually relate to it, unlike college lectures.

[reggidemechko]

I can't thank you enough. This whole semester I was so confused and as soon as I found your videos I aced my test. You are an amazing teacher!

THANK YOU, VERY MUCH, FOR MAKING THIS SO COMPREHENSIBLE!!!! I'M EAGER TO KEEP GOING!!!! THIS IS GREAT!!!! NOW, ...WHERE CAN WE "APPLY" THIS KIND OF MATH???!!!

[Mahdul]

I m truly grateful to you for your derivative lessons....
stay blessed.

Now I got a better understanding of Product Rule instead of using the textbook.

[withtheruths]

Wow I wish I would have found your channel before my first calculus exam (which the entire class bombed the professor curved it by 50 points). Thank you so much for making these videos you are saving me rn!!

I am impressed by seeing your video i everything about calculus now thanks a lot

My tuition fees should go to you instead

True, the order does not matter in this case, but since the quotient rule (where the order does matter) has f'g as the first term in the numerator, it is best to always start with f'g. Then you'll never run into doubt.

Great video man 😃 I like the positive vibe!
Thanks for the help.
