comment Copy a variable to a specific kernel in Mathematica
Then you can still do what I suggested above, just with a subset of Kernels[]

comment Copy a variable to a specific kernel in Mathematica
I can't answer your question and honestly I'm not completely sure what you are trying to do, but for the second snippet of code you would use something along the lines of With[{var2=var2},ParallelEvaluate[var=var2]]. Also note that mapping over Kernels[] is not necessary as by default the command is evaluated on all available kernels.

comment How can I calculate the limit without using the L'Hopital's rule
Nice, I like this way much better :)

Ok, we will see what the OP says anyways.

I am guessing this is math homework and should be migrated, don't you think so?

comment Make Sinc'[0] return 0 instead of Indeterminate
I of course agree that you need to take the limit but the same reasoning could be applied to Sinc alone. So I agree with @Rojo above that the reason to have a Sinc function should be that you don't have to evaluate Limit[Sin[x]/x,x->0] every time. It would be nice if the same was true for Sinc'.

comment Double integral with variable in the limits
@AlexeiBoulbitch Can you elaborate on your comment a bit? I would be interested what you mean with quasi analtytical. Also, how do you know it's not dimensionless?

comment Integration of DiracDelta
I think it would be nice to replace the integration region in the first integral by R^3 though.

You could try posting this at Cross Validated first to identify an appropriate method to tackle this problem...

comment Redefine ArcCot to be inverse of range [0, Pi]
It's well known that compilation does not use user defined rules for built in functions (at least for some of them, I'm not sure if it's true for all of them). On the other hand I don't think it's surprising that things like this happen when you redefine protected functions. An easy fix is to define your own...

comment Redefine ArcCot to be inverse of range [0, Pi]
Falling back to the original behaviour is most probably due to auto-compilation, which uses the built in functions. This can be circumvented by using an additional Evaluate or in the case of Plot by the option Evaluated->True.

comment Bug in RepeatedNull?
Just an observation: f[s : {_[___] ...}] works in the "special case", but does not do what you want in general...

Oh, now I know what you are saying... sorry for that! Now I'm puzzled myself :)

@rm-rf Can do, I thought we might want to keep the OP puzzling for a bit :)
