I tried many videos on this kind of problems, but this one is the best, finally I got this. Job well done. Thank you.

I was so sad to move on to Calculus and not have your constant help anymore. But here I am at the tail end of my Calculus semester and you reappeared! I think you should do more Calculus videos!

I have been an engineer for almost 10 years and a tutor for about 15 years. They do an absolutely horrible job at teaching this in school without any context whatsoever...take this number and follow this process. Almost all of my students give up on math when they get to this concept.

this is irrelevant, but the sound you make when writing on the board is really nice.

This helped a ton, mainly because I forgot about the Summation Formulas.

I have a test tomorrow and this really helped, but the one question I still have is the reason why high school kids like me are required to learn something that I will never use again, especially since I hate math with a passion. But maybe that's just me.

Hi! Is this a right endpoint approximation? I'm really confused. Could you please tell me how the formula would be different for left endpoint, right end point or midpoint approximation. I've understood how to do the problem but I'm not sure what would be different if I was asked to do midpoint or sth else. Thank you!
