comment Intuitive meaning of the probability density function at a point
you're asking about the "physical" or "practical" explanation of the meaning of the value of the pdf at a specific point?

oh I had overlooked that! :)

you're using "greater" as "greater or equal" though :)

comment Is f(x) = x smooth?
@IllegalImmigrant yeah technically smooth is $C^\infty$, but many times for all the calculations we only need our function to be $C^1$ or $C^2$ or something.. so we abuse the notation and we call those function "smooth", which basically comes to mean "it's regular enough to employ all the theorems we need with no headaches"

comment How prove that $e^x=\sum_{k=0}^\infty \frac{x^k}{k!}$?
Nice ;-) you miss a limit in the last formula though :-)

comment Software that uses Cardano's method to solve a cubic?
to do such timing tests you usually need to write the code yourself, or to copy it from someone else (with his permission). How are you going to time the speed of the software otherwise? Certainly not with a wrist watch ;-)

@Mathnix I just added the formal definition for $C^1$ domain as I did not find it on wikipedia ;-)
