## Graph Scatter Plot and Function on same Axes...

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!!!!

## string to list...

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. >solve({a1^2*alpha+a2^2*beta=a1, 2*a1*a2*alpha+a2^2*gamma=a2, a1*b1*alpha+a2*b2*beta=b1, a1*b2*alpha+a2*b1*alpha+a2*b2*gamma=b2, b1^2*alpha+b2^2*beta=a1+b1, 2*b1*b2*alpha+b2^2*gamma=a2+b2, a1*b2<>b1*a2},{a1,a2,b1,b2}); >convert(%,radical);

## Slow summation in a procedure...

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 := evalf(exp(-1*lambda)): f := 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 + g); for i from 1 to (u+t-1) do

## Formating live math output in a document block...

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

## How do I plot a 4-D object (pentatope)?...

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.

## list/sequence values with units...

A couple of question on the following snippet.    ## Published/online articles about Maple TA?...

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

## Plot something of the form x+y+z=3 for a range of ...

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.

## Making help pages appear as worksheets...

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?...

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

## Efficiency in Mapel T.A. algorithms...

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')); ```
