Thank you.

Yes, 2 more values were calculated, which leaded to a slightly different than uniform distribution - that was how I noticed that. Another problem with that is for n=m-1 - for example for m=2 and n=1 (and for n=m) - then one of the array indices used becomes 0, which gives an error.

Comments seem to not moving posts up in the Recent tab, so they very well can be missed, especially for 1 or 2-day, or older posts. I think, I saw another post or two about that.

Will,

Is there a limit on how many points one can lose in a single day?

An interesting procedure.

It seems as if it should be m-n+1 instead of m-n-1 in randV.

It's easier to use another formula, which doesn't require limits,

tan(x+Pi/2)=sin(x+Pi/2)/cos(x+Pi/2)=

(sin(x)cos(Pi/2)+cos(x)sin(Pi/2)) / (cos(x)cos(Pi/2)-sin(x)sin(Pi/2)) =

-cos(x)/sin(x) = -cot(x)

Associated text to the image with the plot command looks as follows in Firefox,

'plot'(sin(t^2), t=`0`*`..`*`3`, labels=[sqrt(time), amplitude])

In other words, 2 multiplication signs were added to the range.

Yes, images were very nice - I remember them. Good luck with restoring them!

Alec

It doesn't work very well. In particular, mathematical functions, such as sin, cos, tan, cot, log etc. should be roman, and variables, such as x,y,z - italics. Now, see

It is not very well. It is not even normal. That's how it's supposed to look,

The easiest way to provide such type of quality would be using jsMath . It is just few javascript files - very simple installation, and a lot of fonts, which are available in both image formats and installable, with even better quality.

http://www.mapleprimes.com/recent/all maybe - with 25 minutes or so delay - unlike it used to be, and with a lot of garbage in it from time to time - that is supposed to be fixed in time though.

On Windows, I would start in that order. In Linux or Mac - in reversed.

Scipy is a part of both Python(x,y) and Sage - and I'm not sure about Reinteract, because I don't use it that often, while it's certainly good for some purposes, and complements the other two.

Now, since you can't vote up this my comment, you still can vote up one (or more) of my other posts as a token of grattitude :)

I would certainly appreciate that (especially in the situation when so many of my posts got voted down - in particular, that one.)

If it's not on their web site, it may be not publicly announced.

But the idea is - contact their sales representative, try to negotiate a reasonable price, subscribe to one (or more) of their newsletters, wait for one or two months - and you might get it cheaper than for Student Edition price.

Scilab and Octave used to be good alternatives (while Octave is kinda slow), but now, I think Python's Numpy is the best one. It is available standalone, as well as a part of Python(x,y), Reinteract, or Sage distributions.

The problem is stated in the subject - the series add assumptions on x. It becomes x~ after using series. Should I repeat the subject in the post?

Another problem was discovered by Alejandro Jakubi - the series is not calculated in Maple 14.
