Discussion Overview

The discussion revolves around the solvability of a specific equation involving derivatives, as well as the method of characteristics for solving a different ordinary differential equation (ODE). The scope includes theoretical exploration and mathematical reasoning.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested, Mathematical reasoning

Main Points Raised

  • One participant questions the solvability of the equation \(\frac{dw}{dv}_{atw0}+\frac{dv}{dw}_{atv0}=0\).
  • Another participant suggests two potential solutions: \(w = i v + C\) and \(w = -iv + D\).
  • A later reply acknowledges the suggested solutions without further elaboration.
  • A different participant introduces an ODE, \(dy/dx = (2*y^2 - x^6)/(x*y)\), and seeks assistance in solving it using the method of characteristics, specifically looking for ground characteristics.
  • One participant critiques the relevance of the ODE to the original thread, suggesting that it should be discussed in a separate thread.

Areas of Agreement / Disagreement

There is no consensus on the original equation's solvability, and the introduction of the ODE has led to contention regarding the relevance of the posts. Multiple competing views remain regarding the applicability of the method of characteristics.

Contextual Notes

The discussion includes unresolved aspects of the ODE and its characteristics, as well as the assumptions underlying the proposed solutions to the original equation.

Is the following formula solvable?

[tex]\frac{dw}{dv}_{atw0}+\frac{dv}{dw}_{atv0}=0[/tex]

Thanks very much~

o,thanks a lot~
 
i am trying to solve a ODE using the method of characteristics

now i found this equation, but i can't solve it:

dy/dx = ( 2*y^2 - x^6)/(x*y)the solution of x = x(0)*exp(y*s)
s is the parametrization

the equation that i am trying to solve:

xy* (du/dx) + (2*y^2 -x^6)*(du/dy) = 0 x>0 y => 0can someone help me. i have to found the ground characteristics
