Solving partial differential equation

Click For Summary

Discussion Overview

The discussion centers around solving a specific partial differential equation (PDE) given by (∂α/∂t)=G[sub(α)] *(a'-a). Participants express a need for assistance in understanding both the derivation of the equation and methods for solving it, with an emphasis on classification and properties of the equation.

Discussion Character

  • Homework-related
  • Technical explanation

Main Points Raised

  • One participant seeks help with solving the PDE and expresses uncertainty about its derivation.
  • Another participant asks what attempts have been made to solve the problem, indicating a need for more context.
  • A different participant requests information about the article providing the equation and its context, suggesting that understanding the background may aid in solving it.
  • Further inquiries are made regarding the participant's knowledge of differential equations, proposing that classifying the equation could help narrow down potential solution methods.

Areas of Agreement / Disagreement

The discussion remains unresolved, with no consensus on the solution methods or the derivation of the equation. Participants are exploring various aspects of the problem without reaching an agreement.

Contextual Notes

Participants have not provided details on the assumptions or definitions related to the equation, and there are unresolved questions regarding its classification as an ordinary or partial differential equation, its linearity, order, and the nature of its variables.

Hi all ,

I would like to solve the following partial differential equation.

(∂α/∂t)=G[sub(α)] *(a'-a)

I attached the equation and solution here as an image.
I don't know how it was derived.

I hope someone can help me

What have you tried in attempting to solve the problem?
 
none yet...The article that I am reading just gave the equation and the answer but no detailed solution
 
What is the article? The context of the equation? What is it trying to tell you?
 
And: how much do you know about differential equations?
can you find the following properties:
ODE or PDE?
linear or nonlinear?
order?
dependent variable?
independent variable?
Classifying the equation will narrow down your solution methods.
