Hi there, I'm trying to integrate some experimental data. I'm sure that what I'm doing is not the best or most convenient way, but I think it should work. I read the data in using the import assistant, which put it into a 2d matrix. I then manipulated that matrix.
This is heat capacity data (for those of you familiar with physical chemistry), and I'm baselining the h.c. data to zero before I integrate it. This hasn't presented any problems for me, and it (seems to) give the expected result.
When I integrate this baselined data, however, the integrated curve (enthalpy) at low values of x is not close to zero; it is much bigger. The integrated curve's topology is what I'd expect, it is horizontal at small x values. It is just off of zero by some (large) constant. My data starts at about 300, ends at 360.

How do it find fibonacci prime numbers using Maple?

Hello,
Can anybody suggest a workaround for the error I am getting?

Okay, I know Maple's not giving the wrong answer...I'm sure I'm just asking the wrong way. When I ask for the standard deviation (Statistics:StandardDeviation) of a list of individual data samples, I get the expected answer. However, when I provide a list of values and a list of frequencies, I don't get the answer I'm expecting. Hopefully the attached worksheet will make my problem obvious.

Hi,
I'm trying to set my MathML viewer to update constantly, as a certain animation in a plot changes. I would either need some type of "time delay" device since the animation works by millisecond delays (which I am able to control), or some type of animating function that isn't for plots, but for procedures. Basically, I am looking for a way to use Set or SetOption over and over again, at specific intervals, without having to click a button or perform a certain action each time the option changes. Thanks for any help.

Hi everybody!
a few weeks ago I asked in this forum a question:
http://www.mapleprimes.com/forum/partial-differetial-equation-heat
First I have to say that is really nice how easliy it solves the problem.
Now, I really need to see values in the solution (I mean, by given x and t).
In addition, I want to create graphs of the temperture as a function of t (I mean to state x, and then to check the temperture as a function of t in this x). Only I know is to do graphs of the temp' as a function of x)
How can I do all of those things?
Thanks A LOT !!!

Is there any way to plot more than one pointset on the same graph using pointplot. On my worksheet the following worked
plotpoint(points,color=red);
plotpoint(points2,color = blue);
But not
plotpoint({points,points2},color = [red,blue]);
or
plotpoint([points,points2],color = [red,blue]);
Any suggestions?

ok me again,
I have this economic problem.
Dc( pc , pt ) = 2000+1000*pt-2*pc
Sc (pc) = 23*pc
how can I plot this, and If I don't know what the value of (pt), can I still plot this?
thank you so very much in advance.

how do I find the value of (p) that will make an equation equal to an other.
ex: D(p):=82-0.75*p
and S(p):=1.3*p
how do I make maple find the answer. ( I know its way more easy by hand, but I would still like to know).
thank you ! Jp

I'm just trying to draw a Petersen graph with one vertex removed, using Maple 10:
```
with(networks):
P:=petersen():
Q:=duplicate(P);
delete(1,Q):
draw(Q);
```

I don't see anything wrong with these commands, and yet I get an error message:
"Error, (in draw/concentric) not a list of vertices [1,2,3,4,5]"
Yes, I know that - I've just deleted vertex 1. But surely I should still be able to draw the resulting graph? I know I can fiddle about with "Concentric", but I don't want to...
And another thing: the inplace implementation of "delete" is, I think, contrary to reason. I would rather have:

Does anyone know how to draw a triangle in 3 space with three points? Also, I need to plot 3 vectors on the same graph. Thanks

Dear All,
I'm working on a problem in differential equations where I need to compute the n-th power of a differential expression. Can Maple be taught to differentiate polynomial functions without carrying out the multiplications / simplifications that it usually does? For example:
diff(-2*c/x^3,x); gives the answer 6*c/x^4.
I want it to return: (-3)(-2)*c/x^4.
Ideally, I also do not want it to simplify sums of such results.
Thank you very much, I appreciate your help!

Okay, well...we're using maple for our math lab in our school and we tried to work on our project.
We had this matrix:
A := RTABLE(419945880,MATRIX([[a, a, a, a], [0, 0, 0, b], [0, c, 0, 0], [d, 0, 0, 0]]),Matrix)
And when we tried to get the inverse, it would just lazily respond:
Inverse(RTABLE(419945880,MATRIX([[a, a, a, a], [0, 0, 0, b], [0, c, 0, 0], [d, 0, 0, 0]]),Matrix))
And it's been working like that for other matrixes, I don't know if I need to configure maple in a different way or something...?

I am working on a project in Maple 10 that was originally designed for Maple 9.5. I am trying to define the weighting function wt. The problem is that the instructions say to type the following command line:
wt := n -> if n=0 then 1
elif n=NInts then 1
else 2 end if;
However, when I do, the following error message shows up with the phrase "n -> if" highlighted in a red box.
"Error, invalid inline function
wt := n ->if n=0 then 1 elif n=NInts then 1 else 2 end if;"
Thank you for your help.

I wish to factor the following:
r^4 +10*r^2 +9*r = 0
I have entered it in Maple 10 as:
factor(r^4 +10*r^2 +9*r);
and I just get a repeat:
response: r^4 +10*r^2 +9*r
Am I doing something wrong or can not Maple factor this?
I'm fairly new to Maple.
Any help would be appreciated
