Hello I am from India. I wanna know why are programming engineers taught physics and chemistry in 1st year? Mathematics is helpful in further years but these two?
i got y=x² y' =2x y'' =2 ζy=x y'/y''=x=ζy i cant make sense of the given solutions. eg y =x² +f(x) y'=2x +f' y''=2+ f'' (y'/y '')² = x²+f (2x+f')² =( 2+f'')²(x²+f) 4x² +4f'x +f'² = ( 4+4f''+f''²)(x²+f) = 4x² +4f + (4f''+f''²)(x²+f) so 4f'x+f'² =4f+f(4f''+f"²) + (4f''+f''²)(x²) cant see it
I also got y=x^2 by looking for a power law solution (assume y = a*x^b and solve for a,b). If you take the expression at 7:25 and let c_1 = 0 (a solution, but not the most general one), then solve for y, you get y = (x+c_2)^2. So y = x^2 is the solution for the case where c_1 and c_2 are both zero.
I did the same as you... but it is hard to solve without WA and Lambert's W
As soon as I saw that ln(...) I knew it was going to feature a W.
Hi.I can solve this solution in 2 line.this is very simple and easy.
I can mail it if you want
my solution is very different and practical for each kind of these issues
sure

Probably to understand basics of topics in which you probably will work. Chemical engineering, construction, and science require a lot of programmers

Okay 👍🏻
Lovely but a bit rushed at the end.
Ooopsies
i got y=x²
y' =2x
y'' =2
ζy=x
y'/y''=x=ζy
i cant make sense of the given solutions.
eg y =x² +f(x)
y'=2x +f'
y''=2+ f''
(y'/y '')² = x²+f
(2x+f')² =( 2+f'')²(x²+f)
4x² +4f'x +f'² =
( 4+4f''+f''²)(x²+f)
= 4x² +4f + (4f''+f''²)(x²+f)
so
4f'x+f'² =4f+f(4f''+f"²) +
(4f''+f''²)(x²)
cant see it
