The answer to your question is yes. Google books link here: Regards, Georgios Kokovidis Dräger Medical

Greetings. From the help pages: The stats package has been superseded by the Statistics package. As far as explaining the difference, I will defer that to others with much more experience than myself regarding this package. There is a lot of overlap here. I am familiar with the stats package and I have example worksheets that I created over the years that call the stats package, so I continue to use it. Here is the Statistics version of the previous example. > restart: > with(Statistics): > dist:=PDF(Normal(0,1),x); > plot(dist,x=-3..3); Regards, Georgios Kokovidis Dräger Medical

Look at the help pages for the statevalf command. In the code segment below, inside the square brackets: 0 is the value of mu - the mean of the distribution 1 is the value of sigma - the standard deviation You can alter these values as you wish. >restart: >with(plots): >with(stats): >plot(statevalf[pdf,normald[0,1]],-3..3); Regards, Georgios Kokovidis Dräger Medical

Explanation here with a reference to the TI calculator. >?describe[linearcorrelation] for more help on this function as it applies to Maple. This will return (r). Squaring the result will return (r^2), which is what you are looking for. To use this, you must load the stats package. >with(stats): Regards, Georgios Kokovidis Dräger Medical

One more way to plot points. >plot([[1,1],[2,2],[3,5],[4,4],[5,3]],style=point); Regards, Georgios Kokovidis Dräger Medical

Have you looked at the VariationalCalculus package? I don't know if it is relevant, but there are functions there that might do what you want. ?VariationalCalculus/Weierstrass or ?Weierstrass will bring up two separate help pages. Regards, Georgios Kokovidis

Here is a crude way to do this without using a program. A "better" way would be to use plot3d and spherical coordinates to define the functions for x, y, z. x = r sin(theta)cos(phi) y = r sin(theta) sin(phi) z = r cos(theta) r=radius > restart: > with(plottools): > with(plots): > c := sphere([1, 1, 1], 3.3): > d := sphere([3, 3, 3], 3.3): > e := sphere([6,6,6], 3.3): > f := sphere([9,9,9], 3.3): > g := sphere([15,15,15], 3.3): > display(c,d,e,f,g, scaling=constrained, style=patch, axes=boxed,insequence=true); After execution, right click on the plot, go to Animate, and click the play button. ?animate ?plot3d ?sphere for more help on the above commands.

Force of habit on my part. Thanks for pointing this out. //Georgios

The link below is from a previous thread here. Credit goes to Joe Riel. Make sure you use the command >with(plots): first, then cut and paste the one line command from the link and execute. You can click on the graph and rotate it as you like. http://www.mapleprimes.com/forum/gabriels-horn-in-maple Regards, Georgios Kokovidis

Greetings. I was hasty with my response. I executed the whole script and the dsolve error pointed me in the wrong direction. You are correct with your observation, but I do not have an answer for you at this point about parameter passing into LSSolve w.r.t. dsolve. If you figure it out, I would be interested in the solution myself. Regards, Georgios Kokovidis

Your error has nothing to do with LSSolve. It has to do with the dsolve command not getting an initial condition. You can use the code below as a starting point. Once you work out the details you can create a proc. The result is a plot of your data with the solution to the diff equation using your numbers substituted for the variables. >restart:with(plots): >data := [[0,95], [11,425], [22, 928], [33,1358], [44,1589], [56,1683], [67,1724]]; >plot(data); >pdata:=plot(data): >DE1:=diff(y(t),t)=(0.09/0.3)*y(t)*(1-(y(t)/1750)^(0.3)); >evalf(dsolve({DE1,y(0)=95.0})); >eq1:=plot(.3943168506e38*(1/(.2022284188e11+.2824308462e11*exp(-.9e-1*t)))^(10/3),t=0..67, color=green): >display(pdata,eq1); Regards, Georgios Kokovidis

No student version. There is an e-book called Global Optimization with Maple. The toolbox is not necessary for this e-book but in order to re-execute the examples you will need it. Look at the Optimization routines and the example worksheets built into Maple. >?Optimization will take you to the right page and from there you can navigate to the example worksheets. Hope this helps. You can also post a specific question to an Optimization problem you are trying to solve and see if anyone has solved this before without the use of a toolbox.

Looking back at Joe's posts and at yours Jacques, I'd say every ten of mine is maybe equal to 1 of yours. If I had 1/10th (notice the exact Maple representation of 0.1)of your skills, I would consider myself a Maple pro. Regards, Georgios Kokovidis Dräger Medical

Maple 10.06 WinXP Classic Interface: I cut and paste your code from above. The plots look identical. What do you mean completely different? Do you have some other code before the call to plot that might alter your image. >restart: >plot( x^2, x=-1..1, view=[-2..2,-2..2], axes=NONE); plot( x^2, x=-1..1, view=[-2..2,-2..2], axes=BOXED); Same size plot in both. I have the plots displayed inline, not in separate windows. Regards, Georgios Kokovidis
