What this links to is units in the ring Z[rootk]. Every unit has norm 1 and thus is a solution to the equation. Clearly units form a multiplicative group.
But now the most important part: how do you find that "first solution" - and more importantly, enure that it is the first (i.e. smallest)? Guess and check sounds very involved for equations with non-trivial coefficients, e.g. x²-73y² = 1217
That notebook was the least asian thing in the video.I can confirm that every competitive exam aspirant prefers longbooks(400pgs+) for exam prep because it is easier to maintain and search old things.
Squaring 9+4*5^(1/2) gives the pair {161, 72}. (I was waiting for you to give that pair, but I had to figure it out myself.) You can also use this method to give rational approximations of the square root of 5: 9/4, then 160/72=20/9...
so what? this is quite obvious since x^2=(-x)^2 for all reals. we are looking for the solution where x and y have the smallest absolute values they could have and we take the positive one for simplicity's sake. we say that the first solution (x1,y1) is the one for which |x1|
@ yeah I’m just saying these are solutions too that weren’t mentioned since it was asked if these are all the solutions in the video, wasn’t a major point.
If "f" is a differentiable function on the interval [0, 1], with the following boundary conditions: f(0) = 0 f(1) = 1 Then, find the minimum value of the integral: ∫ from 0 to 1 of (f'(x))² dx.
What are the tens and the units digits of 7^7^7?

Exactly, how do you even know a solution exists for all nonsquare k?
You can use continued fractions to find the smallest solution and then build the others from that
@@SyberMathi don't it is so obvious how to use continued fractioj for that
Great! Please do make that video showing there are no other solutions!

Nice to meet you ❤ Tomorrow morning I have mathematics exam wish me success
Same here
good luck!
Good luck! Calc exam?
@ of course bro ,thank you
good luck,,
Wouldn’t negating x values also give solutions so we also have all the reflected values

Happy new year y'all!! 🎇🎇🎇🎆🎆🎆
I want to see the proof! Also, can this be extended to when the right hand side is composite?
Very well explained 😊
Amazing video! Happy new year to everyone. 🎉🎆
OK, now how about doing this for x^2 - 61y^2 = 1 ?
Nice proof!
Very interesting!
And for that matter, is there a simple way of finding all integer solutions for elliptic curves of the form y^2 = x^3 - x + r^2 ?
1:32 later is when? give me timecode so i can watch and understand every step not just seing something and forgeting about it
I may not understand the math completely but the video is amazing to watch
The pell equation x^2-2y^2=+-1 gives approximation of square root 2
Secant ,tangent/k are all of the solutions.
張耕宇學長好!
你好⊙ω⊙😊
The thumbnail is so cool
In my classes, we solve this by having the solution be a continued fraction and just write answer in continued fraction format
I dont understand anything, I just watch these to fall asleep
The Chinese are very smart thank you
Sorry, I really need comments for this gentleman.

Can you find a room with more echo? 😂
im in 9th grade, I cant even do basic calculus

If "f" is a differentiable function on the interval [0, 1], with the following boundary conditions:
f(0) = 0
f(1) = 1
Then, find the minimum value of the integral:
∫ from 0 to 1 of (f'(x))² dx.

I will find god
X=i^4 is solution of sqrt(x)=-1
its not
Sqrt(i^4)=i^2=-1
@nouarislimani sqrt(i^4) = sqrt(1) = 1, youre thing is wrong cuz whenever you do sqrt(x^2) its always equal to |x|
In mathematics we have a definition- √(x)² = |x|. Here it's √i⁴ = √(i²)² = √(-1)² = |-1| = 1. So this isn't possible.
Also with that logic in mind you can say that (-1)² is a solution too.
He has good knowledge of mathematics

wow, that's so cool
