Carl Love's answer is great, but I have one thing to add for completeness.

 

From the Maple Help page on the 'series' command:

"The series command gives a generalized series expansion.  This could be a Taylor series or a Laurent series or a more general series."

This means that the returned series may not necessarily be a Taylor or Laurent series.  It just so happens that here the returned series are, but for exactness it might make more sense to use 'numapprox:-laurent' and 'taylor' which are designed specifically to find Laurent and Taylor series expansions respectively.  So, some alternate code is:

a:=numapprox:-laurent(exp(1/z), z = 1);

b:=taylor(exp(z), z = 1);

 

The series aren't exactly the same, but I think the original poster meant for the series to be evaluated at z=1 as well i.e.

 

eval(a,z=1);

eval(b,z=1);

 

which both return e.

I'm not sure if this is quite what you are looking for, but you can extract the transfer function information using the command

 

sys5:-tf

 

which returns the transfer function information in a Matrix data structure.  You can then access the desired parts by extracting the appropriate entries from the returned matrix.

Hello,

 

The 'Occurrences' command from the 'ListTools' package expects a list as the input, but you are passing it a vector.  You will need to convert the vector into a list prior to passing it to the 'Occurrences' command.  For example, the following should work:

 

x := 1; y := 3; a := [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]; z := Matrix([seq([seq(a[k], k = x+m .. y+m)], m = 0 .. 2)]); ListTools:-Occurrences(1, convert(Vector(z(() .. (), 1)), list));

 

I hope this helps!

Hello,

 

The 'Occurrences' command from the 'ListTools' package is perfect for this.  For example, the code

 

restart:

a := [1, 1, 1, 2, 2, 3]:

ListTools:-Occurrences(1, a);

ListTools:-Occurrences(2, a);

ListTools:-Occurrences(3, a);

 

should give you the output you are looking for.

Maplesoft has released an update to Maple 16.02 that addresses plotting issues like the one described here.  If you find yourself experiencing a similar problem, it would be a good idea to have a look at the webpage below for information on upgrading to Maple 16.02a which should fix plotting issues like the one described in this post.

The following FAQ might be of use to you:

http://www.maplesoft.com/support/Faqs/detail.aspx?sid=137988

Though the problem in the FAQ isn't the exact problem you have described, it does seem like you are experiencing a similar "fonts" issue and so the same suggestion could solve the problem.  If you are not the administrator of your computer, you may need to get in contact with the person who is the administrator to help you make the changes suggested in the FAQ.

Additionally, you mentioned that you are unable to call your support team due to your schedule.  If you need further assistance on this matter you can always contact your support team via email and avoid the scheduling issue altogether.  If you are from Canada or the USA, you can send an email to support@maplesoft.com or if you are from another country you can find the contact information for the support team in your country here:

Best of luck in sorting this issue out!

Hello Erik,

This error usually indicates that there was a problem during the creation of the license file and, as such, the license files that the machines are attempting to use will most likely be invalid.

I would recommend sending an email to support@maplesoft.com with the two problematic license files attached and a description of the problem.  I'm confident that our Technical Support team will be able to help you out!

Regards,

Todd

Are users of this particular machine prevented from accessing the Windows Temp folder (C:/Windows/Temp)?  We have seen issues of this type before that were caused by users not having the appropriate permissions to access this folder.  I would recommend ensuring that users of the machine are permitted to access this folder.

 

If you continue to have problems, I would recommend contacting our Technical Support team (support@maplesoft.com) for further assistance.

In the subject you mentioned in the differential equation was separable, but as you have written it Maple cannot distinguish this.  In its current form, Maple sees the 2+sin(x) on the left hand side as the argument of the function y.  Since you mentioned the differential equation is separable, I suspect the left hand side is supposed to be y(x)*(2+sin(x)) which is different than what you have entered into Maple.  You will need to use the latter syntax.  For example, the code

 

ode:=diff(y(x),x)=y(x)*(2+sin(x));

dsolve(ode);

 

returns a solution of y(x)= _C1*exp(2*x-cos(x)).

Currently, we do not officially support the use of any version of Maple on Windows 8.  (The operating system has not been officially released yet.)  However, if you contact our Technical Support team by sending an email to support@maplesoft.com and let them know what Maple version you are using and exactly what the problem you are encountering is they may be able to to provide a workaround.

It sounds like you could use some assistance from our Technical Support team.  I would recommend sending an email to support@maplesoft.com describing the issue in detail and someone from our Technical Support team can offer some help!

This was a known issue when running Maple on Lion (10.7) so I think it's safe to assume that the issue is still present when running on Mountain Lion as well (10.8).  You can read more about this in the following FAQ:

http://www.maplesoft.com/support/faqs/detail.aspx?sid=130811 

As noted in the FAQ, although you can't paste images directly into a worksheet, you are still able to insert an image into your worksheet by using the ‘Insert’ menu.

 

 

See the help page that shows details on the 'solve' command:

http://www.maplesoft.com/support/help/Maple/view.aspx?path=solve%2fdetails 

In the 'Using Assumptions' section it is described how in most cases, 'solve' ignores assumptions on the variables for which it is solving.  It gives some suggestions for forcing Maple to inspect any assumptions placed on the variables; Kitonum's suggestion is one of the possibilities.

 

 

 

 

This error message is usually the result of the compiler not being configured properly during the Maple installation process.  I would recommend that you contact Maplesoft Technical Support about this matter by sending an email to support@maplesoft.com .  In the meantime, you can run simulations without using the compiler by choosing 'false' next to 'compiler' under the 'Settings' tab before you simulate a model.
