Changing order of integration

In this video, I show how to change the order in a double integral, thereby making an impossible integral possible to calculate. Enjoy!

Looks like Dr Peyam had a tea with papa Fubinni

There's just something about his vibe, like, WOW ! You genuinely deserve the best in life . Does anyone else see this ?

Dr Peyam, it's incredible how your work from a very distant place from my place (Brazil) can do so much for students like me from here. I really need to thank you.

1:53 THAT is an extremly nice and intuitive way for describing the region....

I spent an hour struggling with these questions and then I found your video. 😭😭😭 I'm so glad I did.
Now I have 0 problem solving these types of question.

Kfc hates when you change your order but i see you have no fear lol
Love the video <3

5:50 ahhhh so that's the whole reason you change the order of integration. Thank you

8:27 A Math quickie is my favorite type of quickie

[duckymomo]

Fubini's theorem is the most useful theorem out there

Your classes are just assume 👌🏻👌🏻👌🏻👌🏻👌🏻. I love to learn from you and become a greatest fan of your classes.

I like your videos and your humour sense!

[FlowMo]

thanks man, straight to the point and well explained

OMG DR Peyam, They just dropped the restriction on your class, I enrolled :).

[MrCigarro]

Thank you. Your videos are really helpful for us... Colegio de Postgraduados, Chapingo, Edo. de México.

Thank you for your thorough explanation! helped me a lot!

[nassmynredzuan]

Great, thanks a lot Dr. Peyam. (outside has to be a constant. thank you)

I also proved that the Lebeasgue measure, cardinality, ect. of the set of differentiable almost everywhere functions is the same as that of the set of real numbers.

thank you for helping me prepare for integration exam

Question how does this help say in evaluation the integral from 0 to 1 when i did it with a computer i got different results as opposed to(1-cos(1)) * 0.5. Also i did sin(x²+y²) and parametrized to get sin(r²) * r dr dΘ and got the same result but had to divide by 2π. Is this a valid approach.
