comment On finding all the positive integral solutions of $x^2+y^2=z^2+1$
even simpler, FindInstance[ x^2 + y^2 == z^2 + 1 && 1 < x && 1 < y && 1 < z, {x, y, z}, Integers] but note this and @2012rcampion form can only apparently find the one {4,7,8} solution.

comment Switch from logarithmic to linear scaling partway along a plot's axis
similarly you can do ParametricPlot[{inverseg[x], Sin[x]}, {x, 1, 100}, .. (perhaps preferable for readability sake )

comment Does Mathematica get Pi wrong?
the precision value to N also includes the integer part. `StringTake[ ToString[N[Pi, 1000001]] , {-1}] -> (*1*) . (add one for the decimal and note no roundoff issue here since the next digit is a 3.. )

comment DifferentialRoot
I added the direct NDsolve approach to the other question. If that's all you need then all this variable substitution is a lot of work for no benefit.

not sure what you mean to do , but this is a completely different figure.

ParallelTable gives me a slew of errors indicating kernels are quitting and beeing restarted, eg. "Requeueing evaluations {63} assigned to KernelObject [21,local \ ,<defunct>]." (It does does complete though)

Using an integer iterator makes it work: Table[testpara[ia Pi/ 36.], {ia, 0, 71}]. Good practice anyway, but it still should work the way you have it.
