A problem of derivation of higher numbers y‘=(x+xy')/xy One is direct derivation on both sides, and the other is multiplication of XY to the left. Why are the results different I'll get extra points if you understand me
The result must be the same
Is the method of "one is direct derivation on both sides" wrong?
Because it's possible that you didn't take y 'as a function when you used the first method to derive y'

Moreover, binary function is a surface, which is a solid, and what graph is the function with more than two variables? When talking about the curve integral of arc length, in the definition, f (x, y) is an integrand function, But shouldn't an arc be a function of one variable? How can it be a function of two variables? It's an integrand. I think I'm completely confused by the concept,
