How do I plot a scatter plot with a vector x and a vector y, and a function y = cos(x).... on the same axes? Please Help!!!!

Hi
Short question version:
ss := ["abcd", " efg", " hijk", " lm_r", " stuv_k"]
How can this be converted to:
ss := [abcd, efg, hijk, lm_r, stuv_k]
(ie just remove the quotation marks.)
Thanks
David
Longer version:
This was meant to be a reply to a previous question posted about 2 days ago, but I have failed to find it. (Sadly I have failed in my attempt to answer his question anyway.) No doubt my lack of being able to successfully use the sort features - are they working properly? (They just seemed to be in a different random order?)
restart:
ss:="abcd # efg # hijk, lm_r, stuv_k":

I'm having a problem to convert my answer to radical term. I've use 'convert' command' but Maple doesn't work.
Thank you for your help.

Hi,
I am having problems with a slow procedure for doing a large number of recursive calculations. Here is the code:
**g_exp := proc(u,t,lambda,beta)
global k, g, f, d, i, t1, sum2, j:**
**g := array(0..u+t):
f := array(0..u+t):
g[0] := evalf(exp(-1*lambda)):
f[0] := evalf(1-exp(-beta*(0.5))):
**
**for k from 1 to (u+t) do
f[k] := evalf((1-exp(-beta*(k+0.5)))-(1-exp(-beta*(k-0.5)))):
g[k] := evalf((lambda/k)*sum(i*f[i]*g[k-i],i=1..k)):
end do:**
**d := array(0..u+t-1,1..t);**
**d[0,1] = evalf(g[0] + g[1]);
for i from 1 to (u+t-1) do
**

In my worksheet I have a variable Q which has a value of 0.000002859716408. I am in a document block and type
The value of Q
and then I press ctrl= and the line reads
The value of Q = 0.000002859716408
But what if I had wanted the value to be outputted in scientific format, e. g.
The value of Q = 2.85972e-06
Is there any way I could have gotten this output ?
Thanks

It's according to my project, again.
I want to plot a pentatope (4-simplex)
with Maple.
I've tried using plot3d with animate but it's look doesn't work.
Thanks for your help.

A couple of question on the following snippet.

I'm trying to find some articles on people's experiences (good, bad, indifferent) about their use of Maple TA. Does anybody know of any good ones? Some time ago I could download articles from the Maple conferences in pdf form, but when I went looking more recently I couldn't find them
Thanks,
Alasdair

How do I find critical numbers of a function or graph,
such as the function, f(x)=abs(x^3-2x^2+1)
????????
Please help me

Hi, how do I plot something of the form x+y+z=3 for a range of x,y,and z? I thought this should be a simple 3d plot, but I haven't been able to figure it out.
Thanks ahead of time.

I am creating help pages for a package, and want an example worksheet to open as a worksheet rather than a help page. For example, clicking the "Package Overview help page template" hyperlink on the "Templates" help page brings up a worksheet rather than a help page. The mouseover of the hyperlink implies it was saved as a help page (presumably in a help database) rather than as a worksheet.
I see the active=true option under INTERFACE_HELP, but am not sure how I convert my worksheet to this form - surely I would lose the formatting styles.
An option under "save to database" seems logical, or an active=true option for makehelp, but these do not seem to exist.

How can I add blank spaces after each comma in the following
so that the output will be easier to read?
print(X_bar[1] = Mean_SampleMeans1, S[1]^2 = Var_SampleMeans1, S[1] = SD_SampleMeans1);
X_bar[1] = 5.993500000, S[1]^2 = 5.102310060, S[1] = 2.258829356
I am using Maple 10 worksheet mode (Mac). Maple ignores any
additional spaces after commas in the input.
Thanks for your help.

Nowadays i am trying to program a kind of computer algorithm to generate a random mathematical formula, and I'm having an argument with another mapleTA programer, the question is this one:
What is more efficient, have a question for all the types of formulas with random variables or have **only** one question with a code like:
```
$a = range(-5,5);
$ea= range(1,5);
$eb= range(1,5);
$ec= range(1,5);
$eq1 = switch(rint(7),maple('$a*x^$ea*y^$eb*z^$ec'),maple('$a*x^$ea*y^$eb'),maple('$a*x^$ea*z^$ec'),maple('$a*y^$eb*z^$ec'),maple('$a*x^$ea'),maple('$a*y^$eb'),maple('$a*z^$ec'));
```

I'm trying to insert a random polynom in a mathml question, let me explain:
code:
$a = range(-5,5)
$b = range(-5,5)
$c = range(-5,5)
$eq = maple('MathML:-ExportPresentation(($a)*x+($b)*y+($c)*z = 0))
question:

Hello,
is there a way to give new properties to built-in operators, such as `+` or `*`?
For example, I have my own type MYTYPE and procedure for adding MyAdd(a::MYTYPE, b::MYTYPE). Now, I would like to use: a + b instead of MyAdd(a,b). Is it possible?
Thank you.
