These are questions asked by nm

I am using 17.02. I looked at this question, http://www.mapleprimes.com/questions/35783-Inverse-Cosine-And-Sine-Transform but I do not understand the answer.

I have a function F(w), and want to find f(t) using inverse cosine forurier transform.

Here is F(w)

F:= w-> cos(w*L)*cos(w*x)/(w^6+w^2*k);

All parameters are positive.

How can I use the answer shown above, or another function to find f(t)?

I can offcourse simply apply the definition myself, and I did:

int(F(w)*cos(w*x),w=0..infinity) assuming positive;

but the result is

So it does not converge. And I just wanted to check using a build-in function to verify. Strange than Maple does not have these in its inttrans package.





according to this page  http://www.maplesoft.com/products/maple/new_features/codeeditor.aspx

it says "Maple 17 features a completely new editor for writing Maple code."  but for the last 15 minutes I've been looking in my Maple 17.02 for windows and not able to figure where this editor is or how to start it.

When I open Maple, I say File->New-> and nothing there for an editor.

I also looked in my Maple installation icons group, there is nothing there.

I also looked here http://www.maplesoft.com/support/help/Maple/view.aspx?path=updates/Maple17/CodeEditor

"Maple 17 features a completely new editor for writing Maple code.   The editor includes many features to make it easier to write, read, and debug Maple code, such as syntax highlighting, bracket matching, command completion, and automatic indenting. The new editor is available for managing startup code, inline code edit regions, and code attached to embedded components."

but again, does not say anything about how to START it ? Or is this editor a separate apps I need to buy?


One can do igcd(12,8), and igcd(16,3), etc...

But how to define a list/set/array/vector/matrix, etc... that contains these pair of numbers, and then call/map igcd on this list?

I tried putting the pair of values in a list and set and even a matrix, calling calling map(igcd, lst) but not getting it right.

The confusing part for me with Maple is to know which data structure to use for each function, since there are more than one. Here are my silly attempts:




I was looking for something like in Mathematica:

lst = {{12, 8}, {16, 3}};
GCD @@ lst

    {4, 1}

I am sure it is possible to do this in Maple (i.e. map igcd to list of pair of numbers), I just can't get the syntax right. I did look at few examples somewhat related, but did not understand what they are doing. They said I need to pass an extra argument for map in this case?

thank you

Sorry for a basic question, but I am not able to find a setting for this, and I am stil newbie in using Maple UI.

A simple problem. When I copy some Maple code from the net, such as a proc() posted here or else where, then paste the code right into my open worksheet, then each line will show up with ">" at the left.

Is there a way to remove these ">" other than the way I do it now, which is manual process.

Having a ">" at start of each line does not seem to affect anything. The proc() gets defined fine, and I can call it. But normally when I write a proc(), there is no ">" to the left of each line, since those come only when hitting a RETURN. And that is what confuses me.

But what I am looking for, is a way to select some lines, and tell Maple to remove all the ">". Here is a screen shot of some code I just pasted to the worksheet:



I am on windows 7, 64 bit, using Maple 17.02. When opening the command line Maple, and typing:

But on the GUI, it works:


and I get a new window open with the list of package.
In the command line, it works if I use ?index,package;  i.e. without the extra `s` at the end.

On a side question, I was looking at a Maple book, where it said to use ?index[packages];  but this no longer works, even in the GUI, and had to use ?index,packages;  syntax. I wonder when this change happens. The book is old, using Maple 7.
