How do I look for a 9 digit pi-sequence within decimal places of the EULER e  and find the position of that string.

2,71828182..............314159265..........

      123.....................x

can someone show me screen shot how to do this??

thanks so much

I'm new user in maple programming and I trying to constuct a for loop but I taken this Error on my program! here is my program:

This is a follow-up question to my last-name evaluation question a few days ago.

Well, I thought I had got it, but look at this trivial example involving records:

r:=Record(p1=parm1,p2=parm2);

r:-p2;

         parm2

parm2:=0;

r:-p2;

        0

eval(r);

Dear All,

Im trying to model a rigid body, hanging from a string. In the end I have a system of 5 Equations of Motion and with all the Initial conditions I use dsolve. It gives me the error 

Error, (in dsolve/numeric/DAE/isolate) is not linear

I know the system is not lnear but that should be not a problem. One strange thing I notice is that Maple adds these dots in some equations: (the one after 15 but please see original file)

15.*cos(`ϕz`(t...

In the folders Maple 16: there is a file named MapleToolbox_Window.exe. What can I do with it?

The Strengths of maple 16 is Algebra. What the other application of maple ?

Could you help me how to draw this fractal picture in Maple 16. The fractal picture in the website below?

For a while I haven't received notifications about updates to answers and comments from MaplePrimes. Is that due to the recent problem with fake messages from Maple?

in this program, i wuld like to plot R against a, the assign function does not work, can any one help me please????

I downloaded the Maple16LinuxX86_64Installer.bin from Maplesoft and installed Maple16 on my Laptop with Arch Linux X86_64. I started maple using xmaple to get to the Worksheet. When I type a simple instruction as 4+5 and hit the Enter key, I get a error message which says Kernel Connection Not Available. - Waiting for kernel connection. When I cancel that error message another message pops up which say Kernel connection has not yet been established ....... IPv6 is enabled by...

I have been grappling with the Maple concept of last name evaluation and would appreciate a more detailed explanation than is available in the Programming Guide (too brief) or the help page (confusing).

What I think I understand is this: Normally, Maple evaluates an expression fully until all assignments are resolved, leaving me with an expression having only "values" (in a generalized sense, could be strings, numbers, what have you) and "names", which are variables...

I am new to maple. The problem I am facing is to get a non-trivial

solution of a system of odes. But maple gve me only trivial solution.

# The system of odequations I am trying to solve is (Please note that in the bcs phi is alpha.)

# The solution of the above sys of odes is of the form, (note x3=z, its just a typo)

I made a model with mapleSim, run simulation and the following figure was got

Here I have a question. I want to know the max value of this curve that will be used in other component as input in mapleSim. Is here a component in mapleSim or other mothed such as maple?

please help me. think you

Does anyone know why the two integrations of a heaviside function (u1test and u2test) are not equal?  @Preben Alsholm said that the pure symbolic integration u was not correct so that the value of u2test is not correct either. Did I make any mistake in finding u? Is it possible for maple to find the pure symbolic expression of u correctly? Please help!

Hi, I'm having troubles with the conditions in an if statement.  My program is basically a for loop which assigns random values to some parameters, then some numbers are calculated, and finally there is an 'if' that checks if these numbers are positive.  However, when checking some of the output parameters I find that for some of them the conditions are not satisfied, i.e. the 'if' is not doing its job.  Here's a simplified version of the code.  Thanks for any help.
