[@simrannahar8262]

thank you SO much this was absolutely the best

4:21 that's what I was saying from the beginning!! To cancel x with the x

[@haridwarsingh6220]

Nice the way u explain

[@GlobaliveKh]

🤩🤩🤩😍😍😍

[@ss-ew3ke]

thanks a lot from Qatar university!

[@Salamanca-joro]

4:57 you should have used u as well for pi and 0 and change it values

[@HamblinMath]

It's simple substitution, but it's ok to do the substitution explicitly if you need to.

[@morty4082]

Thank you so much Sir! Really help me

[@iZenZation]

Thanks.

[@roseluo1032]

when you use U substitution, but why evaluate in O to Pi ????? U=xy

[@stevemwanza7521]

On which question exactly?

[@catastrophe2155]

why didnt you directly plug the value of 4xy= u and wrote e^u in your second last problem?

[@HamblinMath]

I just skipped that step. If it's easier for you to do the substitution and write your inner integral in terms of u, go for it!

[@akshaykumarsingh328]

Which software are u using to write.please tell me

[@ezzyrush2253]

Genuis People are not good to teach. They think the learner knows everything. Most of the time They explain to themselves

[@JC-uw4gy]

Slow down when you talk, going fast is not teaching

[@HamblinMath]

I recommend pausing the video and replaying any portion that you may have missed.
