comment Is this an error/bug with Plot Command?
@Anoldmaninthesea.: In complex numbers, $x^{1/3}$ is indeed not the inverse of $x^3$. For example, $((-1)^3)^{1/3}\ne -1$. Actually, for even exponents, the same is already true in the real numbers, where $((-1)^2)^{1/2} = 1 \ne -1$. Only for positive $x$ the two functions are inverse to each other.

comment Is this an error/bug with Plot Command?
@Anoldmaninthesea.: Actually, it is not the representation, but the definition of the complex power. It's just easiest described in the polar representation (most probably, internally the formula $x^y=\exp(y\ln x)$ is used, together with an appropriate branch cut for $\ln x$). However see my edit for a function that does what you want (but probably has a lot of room for improvement).

Did you try them separately?

comment C compiler options passed by Mathematica
Does it work if you prefix the space in "Program Files" with a single backslash? Or maybe use "CompilerInstallation" -> "\"C:...bin\""?

comment Plotting on the Raspberry Pi
Yes, I noticed that. Given that it came with the RPi for free, it didn't strike me as odd. Especially since you normally can do everything also with the kernel interface, just less comfortably.

Ah, thank you, I didn't notice that. After I've seen the "Wolfram" Icon, I didn't think of searching for another icon ;-) I now found the notebook interface, and there plotting indeed works fine.

comment How to trigger UNIX command-line command from Mathematica notebook?
@DavidZ: Thank you for that information. I just checked with Run["false"] and I indeed got 256 instead of 1, providing further evidence for this hypothesis.
