Great explanation. I've ploughed through a number of videos on this topic and your video was the only one that finally made things click.

Brilliant!

thank you so much! when you said that you switch which sides had the 2 parallel lines, that is when everything clicked for me. You just saved my grade on my exam which is in less then an hour :)

Peripheral question: can the practice of changing the order of integration be extended to triple or even higher orders of integral? I imagine this would require one to be VERY careful about one's new limits.

@jsm666 Yes, it can be done with triple integrals but it is slightly more challenging. I hope to post some videos about this technique for triple integrals in the future!

Hi Chris, I am not quite sure why after reversing the integral, y lies between 0 and x, why does it not lie between 0 and 1? Thanks

@cd2k85 If that was the case then you'd be integrating over a square, not a triangle. Can you see why?
