2015年8月25日 · $\begingroup$ What I don't see in any of the answers: while for ODE the initial value problem and some boundary value problems have unique solutions (up to some constants at least), for PDE, even linear ones, there can be infinitely many completely different solutions, for example time dependent Schrodinger equation for some potentials admits a lot of mathematically valid, but unphysical ...
Difference between ordinary and partial differential equations
2018年10月9日 · So the temperature of the bar satisfies a PDE - the heat equation. As time goes by, the temperature of the bar approaches an equilibrium state where its temperature does not depend on time, but only on the distance along the bar. The equilibrium temperature (as a function of distance only) can be found by solving an ODE.
Maple vs Mathematica: What's Better for Symbolic Manipulation, …
2004年7月8日 · I've heard Maple is better for various tasks, such as symbolic manipulation, ODE, and PDE solving. However, I've also heard that Mathematica is superior in the field of symbolic integration. I've only used Mathematica (versions 4 and 5), and I'm rather curious about Maple (since I will be using it this upcoming year).
Which Class Should I Take: Upper Division ODE or PDE? - Physics …
2013年11月9日 · The ODE looks like a proper math course. The PDE looks like a fairly gentle tour around a few standard equations and numerical methods (but not necessarily methods that anybody actually uses in the 21st century!) I would say the ODE course is harder and you would learn more, and what you will learn applies to PDEs as well as ODEs.

Difference in numerical approach for PDE vs ODE - Physics Forums
2016年6月8日 · If you use the straightforward finite differencing for a PDE, you usually encounter numerically unstable behavior, which means that the numerical errors in your solution grow exponentially as a function of the time variable t. That is why there are Crank-Nicolson schemes and semi-implicit schemes for solution of PDE:s.
Linear vs nonlinear differential equation - Mathematics Stack …
$\begingroup$ If the ODE has the unknown function and/or its derivative(s) as an argument of a trigonometric, hyperbolic trigonometric, exponential, logarithmic, and/or n-th root function, the ODE is non-linear. If the ODE has a product of the unknown function times any of its derivatives, the ODE is non-linear.
