how to use delta operators OR basic  finite difference methods in Maple?

Please guide me

Δ² f(x) where f(x) = x⁴ , h=1

Hi,

I am a student brand new to Maple.

How can I add a newline in a Maple Input block in Document mode?

Whenever I hit Enter, the code I've typed up to that point - which may be incomplete - is executed. Or, I may need to add a line to some code given to me, but pressing ENTER tries to execute it. (And where in the help system could I find something like that? I looked, but couldn't find it).

Thanks

Hello,

This is my beginnig with maple. This program seems to me very cool, and handy in my study. But I have problem. I want to create a document of project where are simple things but I don't how force maple to show counting.

In maple I do:

x:=5

y:=8

x + y = 13

But I want to show how it was counting I want sth likde that:

x + y = 5 + 8=13

I was looking how to do it but I can't find anywhere.

Please could anybody help?

In the chemical and oil & gas industries it is quite common to describe a gas flow in units of standard volume (e.g. normal cubic meters aka NM3 or standard cubic feed aka SCF).

This is really equivalent to a molar flow rather than a volume flow since the volumes are calculated based on the ideal gas law assuming the flow is at standard conditions (1 atm and 0C for NM3 and 1 atm and 60F for SCF).

I would like to add NM3 and SCF to the SI and FPS unit systems.

There is a difference between a variable with an index and a variable name with an index in "2D Math"-Mode.

The variables look similar.

Here an example, what I type and what I get.

a (SHIFT + _) 1:=2

a (SHIFT + CTRL _) 2:=3

a (SHIFT + _) 1 * a (SHIFT + _) 2

a (SHIFT + CTRL _) 1 * a (SHIFT + CTRL _) 2

a (SHIFT + _) 1 * a (SHIFT + CTRL _) 2

And this is, what I get.

I want to determine the domain of definition for an expression using a command,

but i can't find it in the help,

can someone help me,

thanks in advance.

QuetionLinearize.mwWhen I use 'Linearize' command to linearize a equation, linm:=Linearize(...), it returns a state space or, a differential equation.

Then I want to extract the matrices of the state space, I type linm[a], but failed.

Is there any way to extract the matrices a,b,c, and d from the output? Note that this problem is different from the one which had been submitted.

My operating system is Mac OS X 10.6.4.   Lately Maple has been EXTREMELY tempermental in letting me "Save As a Worksheet"......I'm NOT talking about the "classic worksheet"

I try to save a file with a different name using "Save As A Worksheet" and Maple goes through the whole "Saving Worksheet" routine BUT NO NEW NAMED file is made!

This is very frustrating.....since it wasn't like this before.

Any ideas?

a convex  planar polygon with 9 vertexes such that every its point, which is not a vertex, does not belong to three diagonals of that polygon? This is of interest in connection with a certain combinatorical problem.

I have gotten some comments about my new avatar, including a few commenting that while my picture is clear on the blog contributors sidebar, it is "blurry" on my blog posts. I just wanted clear this up.  I am not in the witness protection program; I just really love singular values.  My new avatar, just like my old one, is a rank 4 approximation of a picture of me using the singular value decomposition.

I lived in the UK before making the barely-considered decision to move to Canada.  I still have savings denominated in pounds sterling (all dutifully declared on my Canadian tax return).  Accordingly, I keep a close watch on the GBP-CAD exchange rate so I have some sense of my net worth.

When I arrived in Canada in July 2008, one pound sterling bought $2, down from $2.30 two years before that.  Today, the pound has devalued further and is worth around...

Hello everyone!

I am stuck after browsing my book and the help section for some time.

How can I find the value of a term like (with MAPLE syntax)

for x=1,2,..,5 ?

I'm looking for something like matlab's k=1:5; operation.

Creating sequences or arrays/vectors didn't help.

Thank you for your time if you read this.

I have recently upgraded to Maple 14, and I can no longer cut and paste syntax between components when I am editing their properties.  Is this normal, or do I have to adjust a setting?

Thanks,

Phil

example.7.mwI have a question for a long time.

For some dynamic systems, I want to extract the matrices or the transfer functions which maple had yielded as a table. The table contains matrices or transfer function.

I want to extract them for other purposes, for example,using transfer function to plot its step response.

Now, is there any way to do this without retyping them manually? Becouse...
