What Do ODE, PDE, DDE, SDE, and DAE Stand For?

[Elwin.Martin]

Okay, kind of a silly question...but what do all of these stand for?

ODE=Ordinary Differential Equations ( ;O I hope this is right, I took a course on this stuff)

PDE=Partial Differential Equations ( Hope this is right too, taking this next semster)

DDE=...?

SDE=...?

DAE=...?

Thank you in advanced!

Only the five? Or we have more categories of these DEs?

DDE= Delay differential equations

SDE= Stochastic differential equations

DAE= Differential algebraic equations
