comment Froze Mathematica and now it's buggy
What kind of misbehavior do you see in NEW notebooks? (i.e. blank notebooks that you create right now, not those already on your machine)

comment RandomVariate form a Specific Distribution with Restrictions
@rka Feeling comfortable with mathematica takes some time. Be patient and keep trying

comment plot both parts of a two-sheeted hyperboloid
@DanielLichtblau Sure, but performs what the question asked for:)

comment Listing all cubic order derivatives of a function of 4 variables
@Mr.Wizard It seems to me the easier way to exemplify its usage.

comment Extracting ragged array from an image
I'm not sure about the fact that DiskMatrix forces you to use integer radii. Anyway, not too important

SeriesCoefficient[Exp[-x^2], {x, 0, n}]

comment Using If statement for more than two cases
Welcome to Mathematica.SE! I suggest the following: 1) As you receive help, try to give it too, by answering questions in your area of expertise. 2) Read the faq! 3) When you see good questions and answers, vote them up by clicking the gray triangles, because the credibility of the system is based on the reputation gained by users sharing their knowledge. Also, please remember to accept the answer, if any, that solves your problem, by clicking the checkmark sign!

comment Plotting the real positive solution to a parametric equation
@AlexeiBoulbitch I would rather say it's a duplicate of this mathematica.stackexchange.com/a/18706/193

comment Plotting the real positive solution to a parametric equation
Plot[x /. Solve[x^2 - a == 0, {x}], {a, 0, 1}]

comment Writing an integral for a bounded volume
Your question is about maths (you need a formula). Sorry but it isn't on-topic here

comment Generate list of strings from a list of assigned variables
@Kuba I believe yours is different enough to deserve its own posting. Ping me after you do that so I can upvote :)

comment How can I transfer colors from first image into second image?
So post it, and we will see what can be done with the colors!

comment How can I transfer colors from first image into second image?
This is a difficult task. You first need to match "objects", and those two images are taken from very different POVs. Not trivial at all.

comment Create an image showing max intensities in a set of images?
I'm not sure. Is it so easy?

comment Function that adds up every element in an array
sum[array_List, i_Integer] := Total[array[;; i]]

comment Plotting Earth's position with units
I'm not sure about what you're trying to do with position[Array[x, Length[earth]]] = x[2], but it seems wrong to me

comment Different results with Plot option “Evaluated” in V9 and V10
Probably a(nother) bug
