Really cool evaluation and great conversion of the fearsome looking nested radical into a sum of two benign radicals. This channel is getting more and more awesome by the day. I would love to have you do all the steps, your evaluation techniques are great and it would do a world of good for serious lovers of calculus, like yours sincerely.
It's really cool i got to know a new technique to integrate the function of this type, i was trying to take x^2 common from the function inside the second root but i got stuck because i thought i will get the square out from but i got extra term I can't integrate thanks to you now i know how to integrate these kind of questions.
Sire, I want to know how much of a positive impact you’re having on this community. It’s not easy to make videos on math and it’s especially difficult to make videos on math that even the most ardent math fans will find hard. That’s what I find especially inspiring about you, you manage to do math like it’s an esoteric craft with its own culture and everything. At least that’s what’s I feel when watching your videos, I don’t feel like I’m watching a math video but a gaming video because you approach it with that same level of passion. I hope you continue to make awesome videos like this. Thank you for this treasure trove of a channel :D
Firstly observe that we integrate even function on interval symmetric around zero but even without this it is quite easy to integrate indefinite integral Euler's substitution twice and you will get rational function to integrate sqrt(x^4+x^2+1) = u - x^2 sqrt((2u+1)(u-1)) =(u-1)w for example
do you do requests? i had an interesting exam question that had d^2y/dx^2 = 8/y^3 as an answer and i was wondering if you could solve the differential equation and get the original equation? the initial conditions are: when x = 1, y = 3
