Not really. A half decent proof would look like this.
[math](-1)^n = (-1)^{2a} = ((-1)^2 )^a = 1^a = 1[/math]
The step where you "arrange them into pairs" and cancel them out there is unecessarily informal.

Assuming I just want to know the density function [math]\rho[/math] of a fluid through time, are there any tranformations I can apply to the velocity vector field/force/etc to make calculations easier?
