 20m comment Archimedes' Scheme to find $\pi$ i don't know that a numerical evaluation would be considered "proof".. 1d comment Integrate fortran function into Mathematica try without the _ 2d awarded Strunk & White 2d revised Double sum in mathematica added 70 characters in body 2d revised Export to excel or CSV file with column and rows. List manipulation required added 49 characters in body 2d comment Change “ListPlot” to 16 bit accuracy? your syntax is wrong, # should be some symbol, eg to16bits[x_] := Floor[2^16*x]*2.^-16 I cant see what that will accomplish though, i.m sure that tiny roundoff is too small to discern on a plot. (Or do you mean to do that rounding at every iteration?)

Anyway NDSolve is not so general that it can handle any sort of bc you can dream up, even if mathematically valid. In this case the pde's look to be fully decoupled, so solve first for u, then use that solution as a bc as you solve for v and so on. Alternately formulate as a single unknown on domain x,0,4 Apr 27 comment Strange DiracDelta integration results in 10.4.1 do the assumptions matter?
