I have several integrals I would like to compute
symbolically; I know Maple has the requisite library
to express the functions.

To simplify expressions and reduce typing errors,
I have done the following:

f := x,s,t -> exp(-(x-t)^2/2 - s*t^2);
g := n,x,s -> int(t^n*f(x,s,t), t=0..infinity);

Both of these give the desired expressions, but
computing g(0,x,s) does not work, nor does

int(f(x,s,t), t=0..infinity);

I have successfully done this by pasting in the
expression for f. What gives?

Combining plots / equations with different time range values

Greetings,

I'm trying to combine two plots then combine those two to get a third
combined plot/equation

This code works with displaying both plots on a single graph but now I
would like to add both equations togather then get a third plot on the
same graph.

The problem is I'm not sure how to add the equations togather with
different time values. For eq1 the time value is from 0..2Pi and eq2
the time value is from 5Pi/3..11Pi/3.

This is the code

with(plots):

I am trying to evaluate a double integral. Maple
reduces it to a single definite integral of the
sum of three functions. Two of these function
are well within Maple's power, but the third is
not, although with Student the third can be
evaluated by integration by parts as an indefinite
integral. How can all of this be put together
without an inordinate amount of manual copying and
translating from Maple's output form to its input
form? In general, computer systems do not believe
that users can contribute to the result.

MI5 Persecution: BBC Newscasters Lie & Deny. They're Watching Me

Central to the persecution campaign waged against me for some. nine years
now by the Security Service is their use of the media,. and in particular
the broadcast media, to. make clear to me that I am under surveillance and
being watched within. my own home, even by BBC newscasters while they read
the news. This is really an act of arrogance; MI5 and their tools in. the
television and radio are so sure that. they can never be caught, that they
have many times made explicity. clear on broadcast programmes that they are
as capable of seeing me. as I am of seeing the broadcast pictures. Even
when they have known I. am taping the programmes they still carry on this
practice;. for examples of TVand radio presenters caught "in action", see
the Evidence area of my. website.

If you. wish to reply to this article......
then please include your name and fax number!. I provide the means for
recipients to send me their thoughts on the topics. discussed, but ask that

Four Years of "MI5 Persecution" Posts on Internet. Newsgroups

For approximately the first three years of. the MI5 persecution, from June
1990 until late 1992, I. kept as quiet as possible, in the hope that by not
reacting, MI5s interest in me would decrease and they would simply. go away
of their own accord.. This is the sort of behaviour some people employ
against bullies; if the bullies arent getting a reaction,. then they might
simply go away and victimize someone. else.

Unfortunately, this tactic didnt work. The quieter I became,. the more
shrill and hysterical the. noise from the Security Service operatives. For
about two years I didnt. watch TV news at all. Yet this only heightened
their obsessed. fixation; they continued to follow me wherever I went, they
continued to. induce harassment at work by managers and fellow workers, and
they continued to encourage me to commit suicide. They seemed to regard. my
refusal to react as a crime which they would have to "put right". by ever
more extreme. forms of abuse.

Somewhere. between 0 and 100%%

The. last few days there have been no clear recordable instances of
abuse. However, while. travelling on the Underground, while walking around
near my home and going to friends homes, I am constantly troubled. by
thoughts that. those people over there might be about to get at me; that
the couple sitting in the opposite seats laughing are in. fact laughing at
me; et cetera,. et cetera.

A comment by a scientist to the BSE inquiry sticks in. my mind. He
described the possible scale of the epidemic as "between. 0%% and 100%%". It
might not be happening, it might not happen at all,. to any discernable
degree.... or it. might be total. Without clear recording, which seems to
have become impossible the. last couple of weeks, there is no way of
knowing. whether the harassment really is continuing, whether we have
entered a temporary hiatus, or whether perhaps it has. perhaps stopped for
now.

BBC newscaster. Nicholas Witchell cant stop himself laughing

During 1990-91 there were very many instances. of "interactive
television" where newscasters and. other TV presenters saw on a screen
before them what was happening. in my home, and reacted, frequently by
laughing at me. During this period I unfortunately did. not record these
programmes. For the last year or two,. I have been recording everything I
watch, and there has been a drastic decrease in such. incidents.

However,. on occasion, television presenters do still engage in
"interactive. watching" and react to what they see. This has been evident
with. Jon Snow of Channel Four News recently - a particularly interesting
case, since it has been established that he cannot be corrupted by. money
(it is well-documented. that MI5 offered him a tax-free salary and he
turned them down). I. wonder what device MI5 are using to encourage him to
do. the "interactive watching"?
