this is why maths is like art- i was wondering if you would start a playlist on problem solving techniques or maybe more systematic organisations of math topics/knowledge/theorems?
@@ashishraje5712 He sets u = y^2 - 1 which is the RHS of the equation y^2(y')^2 = y^2 - 1. But note that y^2(y')^2 (the LHS) can be rewritten as (yy')^2. What is inside the exponent is yy'. Compare this with the derivative of u: u' = 2yy'. Ergo (yy')^2 = (u'/2)^2.

Total agree with ya mate
Yes haha I will make sure to organize and make those playlists my friend👍👍👍
Good solution sir
Thanks a lot my friend👍👍❤️
@@drpkmath12345
Most welcome sir
This is definitely the differential equation of the day
Haha thanks my friend👍👍👍
Nice solution
Thanks my friend👍👍👍
Another great video professor
Thanks my friend haha👍👍👍
1/2y + y/2
Nice! And you can go further👍👍👍
Pls explain u prime square at 2:36 minutes
We have y^2(y')^2 = (yy')^2 (*) = y^2 - 1.
If we ser u = y^2 - 1 then u' = 2yy'. That is yy'=u'/2. Substitute this in (*) and you have it.
@@r.maelstrom4810I did not get (u' / 2)^2 = u, cud u clarify

Nice to share it r.maelstrom4810👍👍👍
Oh
Nice and tricky one professor🎉
Thanks my friend haha👍👍👍
Very nice solution professor
Thanks a lot my friend👍👍👍
