comment Transparency rendering problems in Mathematica 10 (Mac)
I can reproduce the dots you see under Linux. Also, I think that @Thomas is correct. Try this: Contours -> {.9}, ContourShading -> None, ContourStyle -> {{Red,Thickness[0.1]}}

comment Mathematica Destructuring
I just stumbled over this and I have to say I really like it! Using this with the shorthand notation is especially neat!

comment Is there a way to solve the linear equation, Ax=b, in which A is a “non-constant” sparse matrix that depends on x?
@murray I'm a bit confused by your comment... How is it a linear equation if A depends on x at all?

Very neat! Never thought about this one!

I can confirm the exact same behaviour on Linux Mint Debian with both Mathematica 8 and 9.

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.
