I am unable to locate this application.  Ultimately the links on the page I got it from do not contain the downloadable worksheet nor the Maple code.

@Axel Vogt Strange, it wasn't working for me before but it works now.

I don't use twitter so why would I force anyone to use it?

There are applications from Maple V you won't find by search on Maplesoft and if you're just browsing for applications you may never know some exist.  

For example
http://www.maplesoft.com/applications/view.aspx?SID=4049&view=html

Now I should be able to remove the &view=html from the header address and have the webpage come up.  However the page comes up blank!  This could be one of the reasons why the search doesn't bring it up. 

As a shorter version f' works as well

sort(arc,[f'],ascending)

Ah, I see, I have to sort the diff. 

sort(arc,[diff(f(x),x)],ascending)

Thanks for the replies.

So how would I move the 1 over in this general case

You could use randcomb to reduce points.

with(combinat):
a:=yourdatalist

randcomb(a,3000)

However I don't know wether it would retain the fit shape or if there's a similar statistics data sampling of 3000 points (-other mapleprimers - is there?)

Could create a little procedure, but the funny thing is (as a side issue) it won't simplify the same inside the proc as it would outside.

dint := proc (a, b, c, d)
  simplify(subs(b = d, int(a, b))-subs(b = c, int(a, b))):
end proc:

dint(exp(x^3),x,1,2)

simplify(%)
 
whereas outside of the proc

no second simplify is necessary
 

@vv  you did mention it refuses to compute over 1..2 , which is incorrect.  I merely proved Maple does compute the answer. 

Works using numeric
int(exp(x^3), x = 1 .. 2, numeric)

@Carl Love thanks I converted it back to a post so Maplesoft would better notice it and hopefully answer

As far as my records show a Maple 6 search should have brought up 157 applications on the Maplesoft applications search but only brought up 43 applications

Using numeric brings up an undefined nasty

Change the order of your variable ranges in your first two examples, and see if they turn out correct. (I'm not around Maple today so I can't check)

@vv .. whoops yes, a two dimensional probability, sorry I made it out as two combining 1 dimensional probabilities. 

I appologize if the proof is wrong
