comment Function to calculate finite difference
Agree with @Jens. This is not easy to find. You have to already know it is there in order to know it is there! But it should solve your problems.

Or just StringSplit["kspe", ""]

I like your answer ...although I've never liked using Item :)

+1 nice use of negative indexes to avoid rotating functions

@Edmund I find it more intuitive doing it that way but it is up to individual preference

There will be examples in the docs. Maybe start with SparseArray

comment Why DynamicModule does not plot the intersection region and does others?
Dynamic@TranslationTransform[pt][Vertices[Hexagon]]; does nothing. Dynamic updates pixels on the screen so whenever you have Dynamic@Something; nothing is being updated.

comment How could I have each new cell framed?
@kornaros yes. create a stylesheet and add the style. Plenty of examples on this site

it should be possible but it would help if we could see the format of the dictionary you want to import

comment Is there a way to use Table[] without having to calculate my function twice?
Or SetAttributes[MyHugeMessyLongFn, Listable]; Transpose[{Range[5], MyHugeMessyLongFn@Range[5]}]

comment How to track Part of Symbol or How to symbolize Parts of Symbol without copying data
In the past I have done something similar to what @WReach suggests by creating a separate function to take the term with Head Part. Internally you assign a symbol to it and then track that symbol dynamically.

comment Insert the chapter number and title in a header or footer
You haven't provided enough information for anyone to give you a useful answer. Is your mathematical paper in a single notebook? How are the chapters partitioned? For example, if in a single notebook are the chapters all in separate sections etc etc

comment Equivalent command to the Maple indets command
@ChenStatsYu in that case use Maple but use Mma for the stuff that you don't feel that Maple does well, ... or cannot do

comment Equivalent command to the Maple indets command
@ChenStatsYu if Maple works for you and you understand it then stick to it. The time needed to switch to a rival product is rarely worth it if you are proficient in one of the other Ms

comment Equivalent command to the Maple indets command
@ChenStatsYu I think it is unfair to say it sucks at PDE solving. While i used to solve PDEs day in day out I have not done so for 10 years. There are still some problems that Mma cannot solve so you have to roll your own -- which I did cause NDSolve couldn't do it. Also NDSolve is an incredibly complex function to learn if you want to delve into it. Perhaps you should post a question if you are having a problem solving a PDE.

@kguler thanks. it is amazing what you can learn here. I never knew there was Threshold but it's been there since 8!
