I'm new to Vista, and I'm trying to get a network copy of Maple 11 to load correctly. I've read about the open/save problem, so I tried to run the install file as administrator under Windows 2000 compatibility mode, but the installation wouldn't finish properly, so I installed normally. Opening normally, Maple now runs fine except for the open/save problem. Opening as administrator andd under Windows 2000 compatibility mode, the program stops working before it finishes loading. I don't know what to do, I need this program for class. Please help.

how do i solve a matrix ^ 10?

thank you

Actually, I could just cut to the chase here...

I need to print out a 2-D ring and then attach that to a 3-D sphere.  The problem is that the 2-D ring will buckle as I attempt to attach the outer circumference of it to the sphere.

 

This problem arised in a math forum.

I would like to check wether the consecutive digits of a given positive integer (n) are in the first 100000 digits of Pi.

For example the given integer (n) = 1592653 and this is in 3,1415926535897.... so the result is true.

I also would like to use this pattern matching for checking the type of a variable in a procedure:

myproc:=proc(n::mytype)
...end proc;

The procedure accepts n if n fullfils the condition above.

Hi, I have a trouble in handling MathML in worksheet published by MapleNet. A simple worksheet published on the following page works fine. http://mapleoracles.maplesoft.com:8080/maplenet/primes/worksheet/256_int_math.mw However, same worksheet published on my own MapleNet server does not work nicely. http://thomas.phys.cs.is.nagoya-u.ac.jp/maplenet/App/int_math.mw

I have found this problem somewhere in a math forum: somebody wanted to simplify this expression ( I write it in maple syntax:, this was not a maple forum):

a:=(1253*sqrt(2)-963*sqrt(3))^(1/3)+(26209+10500*sqrt(6))^(1/4);

They tried with the simplify command of maple, but it didn't work, and they tried with Fullsimplify command of the other famous math program , and it worked. ( I haven't tried it.) The conclusion was that Maple couldn't do this job.

Actually Maple can do this job with radnormal:

radnormal(a);

14*2^(1/2)

I am having problems using implicitplot.  I run this code and it worked and today I tried it again and it gives me the following:

with(plots,implicitplot);

implicitplot(0=int(erf(  (T-e*t)/sqrt(2)  )*t^2*exp(-t/2),t=0..infinity),e=0..1,T=0..10);

Error, (in plots/implicitplot) invalid input: the following extra unknowns were found in the input expression: {t}

The weird thing is that this worked before (took about 10min though) and now it isn't.  Any suggestions?

Thanks

 

I want to write some stats questions on forecasting. I would like to have a list which is a time series, and use Moving Average to derive forecasts, then calculate my errors, etc. I can do it all in Maple, but I don't know how to create a list in Maple TA. For instance, how do I create A in Maple TA's algorithm, where A is defined by:

A:= [seq(round(RandomTools[Generate](distribution(Normal(40,5)),1)), i=1..20)];

This is just a  list of some "sales figures" distributed approximately normally.

Thanks in advance

I am trying to plot q2:= (x) -> x*exp(x^2)*(1-erf(x)); for 0 <><>plot(q2(x),x=.1..10); then the resulting plot is incorrect. In reading other posts I get the impression that one needs to somehow prevent the plot routine(s?) from following their default behavior of refusing to compute with the

Hi, I'm hoping someone in here will be able to help me.

I've made two files in which I need to find a symbolic expression for the difference between two mathematical models of a mass, damper, spring system:

Hi,

            I have a question regarding  Chebyshev interpolation of data. How can I interpolate the following data by Chebyshev interpolation using maple?

X:=[16,45,85,120];
Y:=[4,7.2,1.6,0.5];

Thank you

 

I want to have a procedure define a function... If I do: >with(stats); >does_not_work:= proc(t) local v,d0,d1,x,y; > v = rhs(fit[leastsquare[[x,y], y=d0+d1*x]](t)); >end proc; then > does_not_work([[0,1,2],[3,4,5]]); results in "v = 3 + x" as expected, but if I try to have the procedure define a function d as in >does_not_work:= proc(t) local v,d0,d1,x,y; global d; > v = rhs(fit[leastsquare[[x,y], y=d0+d1*x]](t)); > d:= (x) -> v; >end proc; then > does_not_work([[0,1,2],[3,4,5]]); > d(1); does not result in 4, which should be the result of applying
