Oxford Calculus: Solving Simple PDEs

  • čas přidán 9. 06. 2021
  • University of Oxford Mathematician Dr Tom Crawford explains how to solve some simple Partial Differential Equations (PDEs) by treating them like Ordinary Differential Equations (ODEs).
    Practice solving some simple PDEs for yourself with this free worksheet in Maple Learn: learn.maplesof...
    The first examples look at homogeneous first and second order PDEs where we integrate directly and replace 'integration constants' by 'integration functions'.
    The third example looks at the inhomogeneous case and how we can use our methods for solving ODEs in the PDE context.

    I'm a huge fan. I just found the channel by accident, I've taken ordinary differential equations and I'm studying relativity but I do feel like I grasp it quite enough so I love your tempo I love your pace and I'm going to subscribe!
    I'm sorry I meant to say I don't ever feel like I grasp it enough. Stupid voice translation. 😁

    You see, snakes can curve. Curves represent a mathematical change in gradient, linking in to differential calculus, and therefore it is perfectly reasonable that you have just witnessed a snake ad prior to a Partial Differential Equation video.
    Nah I'm just as clueless as you are.

    Really great content, my only question is how do you come up with the guess function with the u variable? Does this come from experience or are there standard procedures for applying a function as your "guess"?
    I also didn't follow the part where:
    u ~ e^mx => m^2 - 1 = 0 m = +- 1
    Where did this part come from?
    Many thanks!

    • @jackpoore7866

      Heat diffusion in a bar is modelled by the 1D heat equation which is a PDE. Also, reaction diffusion equations of most forms are also PDEs. Processing images (like denoising) can be done using continuous PDE based methods. There are so many applications of these- they’re actually everywhere. Hope this helps

      It is not easy to think about an easier equation. Perhaps (f_x)^2+1=0, f real valued, is easier for everybody knows it has no solutions at all.
