Simplification involving radicals in the denominator

Mac Dude — Thu, 10 Sep 2026 14:37:12 Z

I have an expression Vector (result from a lengthy calculation) like the following:

It is obvious by inspection that a minimized for of this expression looks like this:

Proof:

But for the heck of it I can't get Maple to find that result by itself.

My attempts are in this worksheet: Maple_example.mw

TIA,

Mac Dude.

Polynomial systems in Maple 2024

Tomer Damari — Wed, 09 Sep 2026 17:24:37 Z

Add a couple of variables to a polynomial system and the difficulty climbs fast. Maple 2024 helps here in one specific way: RootFinding:-Isolate handles complex solutions of multivariate systems.

Take this one:

sys := [
x + y + z = 0,
x*y + y*z + z*x = 1,
x*y*z = 1
]:

RootFinding:-Isolate(sys, [x,y,z], complex);

Previously you would break that down yourself into a chain of single-variable equations. Now you hand it over whole.

fsolve changed too. For univariate polynomials above degree two it calls RootFinding:-Isolate by default. There is also a PW method, which isolates and approximates complex roots faster in a lot of cases.

Worth understanding what isolation actually does: it locates regions containing roots first, then refines the approximations inside them. That ordering matters when roots cluster tightly or sit in the complex plane, exactly where plain numerical root-finders start returning garbage or grinding.

Maple Installer Question

adityasaroha — Wed, 09 Sep 2026 06:26:41 Z

I specifically want to install the Maple 2024 version as I am implementing a open-source research project which specifically states the requirement of Maple 2024, but in the 15 days free trial version I am not able to to so, can someone please help me!

Adding a library path

Ronan — Sat, 05 Sep 2026 23:28:29 Z

I need to add a library path name to get an old style package .lib to run. Currently a have to manually add the path. How do I solve this?
Also should the package be convverted to .mla type? What is the difference?

Edit;- I am using windows 10

restart

download location https://github.com/fractal97/CLIFFORD

libname

(1)

I have to use the following to get the package to load

>	savelibname:="C:/Users/Ronan/Maple/toolbox/Cliffordlib"

(2)

>	libname:=savelibname,libname:

libname

(3)

>	with(eClifford)

(4)

This is a screen shot of what in in the library folder. It is a older type .lib package

This is what is in the .ini file

#savelibname:="C:\\Maple2020/Cliffordlib":
#libname:=savelibname,libname:
#savelibname:="C:\\Maple2020/Cliffordlib":
savelibname:="C:\\Users\Ronan\Maple\toolbox\Cliffordlib":
libname:=savelibname,libname:

filepathname:=cat(savelibname,"/","define.m"):
read filepathname:
filepathname:=cat(savelibname,"/","definemore.m"):
read filepathname:
read(cat(savelibname,"/","Walshpackage.m"));

GUI is unresponsive

Jean-Michel — Sat, 05 Sep 2026 18:46:28 Z

Hello,

Under Windows 11 Pro the GUI of Maple 2026.1 stuck Maple totally.

I can't even open a new document.

In Maple 2026.0 everything was ok...

This .1 release is unusable on my computer. I didn't dare to ask until today.

Open windows task manager I see that OpenJDK platform binary is the culprit.

Then.. I do NOT know what to do.

If someone has an idea I will be very happy.

Thanks and best,

Jean-Michel

Integrating the derivative of tanh

C_R — Thu, 03 Sep 2026 21:05:35 Z

I could not figure out why Maple does not return tanh. Instead a complex valued function for real arguments is returned. This is not recent. I tried down to Maple 2020. Is that correct?

>	D(tanh); plot(%)

>	int(D(tanh)(x),x);# I expected tanh plot(%);# ok, no plot for real valued x

Warning, unable to evaluate the function to numeric values in the region; complex values were detected

>	int(D(tanh)(x),x=0..infinity);# this result seems to be known in advance and fits to the above plot

(1)

>	int(D(tanh)(x),x=a..b); eval(%,[a=0,b=infinity]);# I expected 1 from (1) eval(%%,[a=0,b=50.]);# retruns complex for small values

Error, (in ln) numeric exception: division by zero

(2)

>	evalf(int(D(tanh)(x),x=0..50))

(3)

Let's try integrating the identical expression sech^2

(4)

>	is((sech^2=1-tanh^2)(x));# check identity

(5)

>	int(sech(x)^2,x);# what I expected
