The equation has no real solutions... but it accepts complex solutions.

@habeebalbarghothy6320 16 дней назад

It's very clear that this eq. cannot be solved

x=y=無限大 1/無限大=無限小。無限小+無限小 =無限小

1/(x + y) = (x + y)/xy xy = (x + y)² y = kx kx² = x²(k + 1)² k² + k + 1 = 0 k = (-1 ± i√3)/2 *y = x(-1 ± i√3)/2* [ complex solution only ]

It's the perfect solution, since the domain of x and y were not specified in the video. Indeed, this is the solution.

hi I have a little lost, why y=kx?

@@daveh1924 parametrization. it's a common way to find a solution.

@@SidneiMV thanks for the reply. Yes your method indeed can perfectly find a particular solution if y and x are proportional.

@alanyoung1711 20 дней назад

@@daveh1924 Any 2 non-zero numbers, real of imaginary are always proportional. Just divide on by the other to get the proportion. This is a fully general solution.

@alanyoung1711 20 дней назад

This is a disappointing video - taking 5 minutes to reach an incorrect conclusion. There are infinitely many solutions to this, indeed for any non-zero choice of x one can find a y that makes it work and vice versa. @SidneiMV is perfectly correct, writing out in more detail: Assume x and y are non-zero, write (1) y=kx for some abitrary non-zero k, so the problem becomes (2) 1/(x+kx) = 1/x + 1/kx Cross multiply (2) by k(1+k) and bring everything to the same side, note that the denominator is non-zero by choice of x and k, and get (3) x^2(k^2+k+1)=0 Since x is non-zero, we must have: k^2+k+1=0. Put this into the standard quadratic formula [-b+/-sqrt(b^2-4ac)/2] to get (4) k = (-1+i*sqrt(3))/2 and (5) k = (-1-i*sqrt(3))/2 Pick ANY non-zero x (can be complex), use (1) to calculate y. Put these values into the original formula and verify the solution (try x=1 as a simple example). Side bar: solutions (4) and (5) are the two complex roots of 1, each of which is the complex conjugate of the other. One can observe this by noting that (k^3-1)=(k-1)(k^2+k+1). Nothing magic, just a happy co-incidence for this problem; if it was solve 1/(x+2y)=1/x+1/y then same methodology would give a different value of k.

Có gì đó sai, nếu x=y= 0 thì 1/x và 1/y ko đúng

@arseniylanin 12 дней назад

What about comlex numbers?

@imetroangola4943 Месяц назад

The emblematic problem in your videos is that unfortunately you do not say the domain of the variables x and y. What you used is true, if x and y are real numbers.

@snarkybuttcrack 24 дня назад

what's the complex solution then?

@timetraveller6643 24 дня назад

Say your name out loud to understand why no-one is going to take you seriously.

@roryd4852 17 дней назад

Except that the author did not specify x's and y's domain, a very clever solution.

@@roryd4852The solution is simple, mathematically speaking. I don't take away the merit of the person who makes the video, my tip is to help the channel to improve more and more!
