Let's say we have a function [math]u(x,t)[/math]. Then what's the physical interpretation of its second derivative in space? So basically, what does [math]u_{xx}[/math] represent, physically?

>>	Anonymous Sun May 21 15:34:02 2017 No.8926437 Depends which variable you differentiate w.r.t. each time.

>>	Anonymous Sun May 21 15:36:19 2017 No.8926440 should still be acceleration. just that it is at a particular time point

>>	Anonymous Mon May 22 02:48:58 2017 No.8927926 >>8926437 this, but also what your original function is modelling >>8926440 if it's modelling distance then yeah it's accelleration
