I corrected the wording and deleted my misleading comment regarding function names combined with operators within the first set of parentheses. With function name I mean f in the function expression f(x) as described in ?function. This page describes function application but not constructs like (function_name operator function_name)(arg(s)) as in (sin + cos)(x). I only find "operators are distributive" in examples,functional. I cannot conclude from that with certanty what is meant by operators and if distributive (?Definition,distributivelaw) applies also for other "things" like -,*,=,^,... inside expr1 of (expr1)(expr2). In any case not all operators within expr1 lead to a distribution of the function application to the argument(s) in expr2. The logic behind does not seem to be descirbed in the help system and examples are missing.

One of the challenges for me was to understand the different meanings of operators, functions, function expressions and mathematical functions (which can be defined in Maple using a functional operator even though most of them are implemented as procedures).

I hope that this exchange describes at least the difficulties one can have learning Maple by using only the help system. AI might change this. As of today AI lacks the exactness of the help system and misses out on what made me courious about (expr1)(expr2) which was in the first place the arithmetic constructs in expr1 using only function names.

To conclude: I understand that ()() is not a special type for syntax. Function application was the help page I missed out (I doubt that the definitions would have been understandable back then).

For fun

I had temporary problem with similar messages. See here:

https://www.mapleprimes.com/questions/242099-Online-Helps-Error-Messages-Links-Blocked

They resolved without doing anything.

If your uploading problems depends on the file contents, that would be new. For this rason I was interested to learn at which stage of the uploding process the error message is issued. Was it at stage "2. click upload" or later.

For completeness:

The use of (expr1)(expr2) is also demonstrated in the examples of the function help page in the context of function application.

(sin, cos)(x);
                         sin(x), cos(x)

Within the same Maple 2026 session. My worksheet

At which point of the upload you get the SQL injection message? Is it at uploading or inserting?

Would it be possible to determine whether the Maple AI code or the ChatGPT code is responsible for this?

It should not be Maple AI because the inserted code edit regions cannot contain hidden code (I assume). If it turns out that third party AI code can inject hidden suspicous/malicious code, Maple users must be informed about this potential risk.

Have you tried an empty Maple file. Just to make sure that it is not a temorary fire wall issue.

Did you also contact MapleSoft by email or via this webform?

Where the prompts and the model you were using. I get no errors here: geodesics_AI.mw

This produces the output you want

NULLInt(``, x)

Int(``, x)

I still do not understand, in which context you want to use this and why non-executable math is not an option.

Yes, everything disappeared.

PackageTools:-Install(4797495082876928)

did not work. I had to use the command I used before

The OS is Windows 11

 

@aroche 

I did

PackageTools:-Uninstall("Maple Customer Support Updates");

and the package was successfully uninstalled.

After restart, I installed from the cloud and got the same installation crash.

For both crashes screenshots are not possible. The tasks are killed.

@aroche 
I cannot reproduce it either on a different computer "B".

On this machine the flie creation date of the Maple 2026 installation shows 13th of march. I will now try uninstalling on the other computer where the problem occured.

 

On the other computer "A" (with supportools version 35) uninstalling does not work. Maple crashes when I do
 

SupportTools:-RemoveUpdates()

Creation date (mouse over on bin folder on Windows 11) of this installation is March 14th. 

 

This is what I get when uninstalling on computer "B"

@dharr 

I remember @Scot Gould complaining about Smart Equation Editing introduced with Maple 2025 but have troubles finding his post. Maybe I am wrong. In any case, "!" is not on the list of enchancements that make

"entering complex expressions faster and more fluid, letting you focus on your work without interruption"

Yes, looks like a bug.
