    Searched the whole internet for this sort of clear explanation, thank you.

    The paint brush analogy really helps to understand what to put for the bounds depending on the order!

    This professor is amazing no one else was actually explaining the set up. I was very confused as to why the dx was being integrated just at 2, this is the first video to explain it. Amazing!

    I've been trying to understand finding the bounds of both double and triple integrals for this whole semester and you've really helped me out. Thank you so much!

    Very concise and apt explanation of whats going on, especially adding up the blocks of numbers part. Thank you so much for this!

    Thank you so much I finally understand bounds. Setting up the blocks and adding them was a great analogy of what double integrals were doing.

    I can see now I wasn't the only one who looked up on how to determine the bounds of the double integral. Thanks for such a clear explanation!

    This was so helpful. And like you said, if you understand this then everything else going forward is a lot easier. I especially liked learning that once you integrate once, it becomes just a sing variable function. Thank you!

      @@daniel_an i ll give u an example of some problem I encountered . lets say R is the sector of the circle of radius 2 centered at the origin above x-axis and below y=x
      firstly I said: SSdxdy= the double integral from 0->1 (of dy(outer integral)) ,integral from square of 2-y^2 to x ( inner integral ) which gave me a wrong number of 1-square root of 2(negative). then I changed my inner integral boundaries ( just turned them around ) and gave me square of 2 -1 which is positive. I hope I was clear xD sry for longpost
