Why can't the commands in these document blocks be...

ODE for electrical circuit (right click on Documentblock, unselect show command does not work. Command still visble)u(t) = T*(diff(`ϕ`(t), t))+L*(diff(i(t), t))+i(t)*R

u(t) = T*(diff(varphi(t), t))+L*(diff(i(t), t))+i(t)*R

 (1)

 

ODE for motor (toggle Documentblock, unselect show command is only effective on equations  3 and 4)i(t)*T = J*(diff(`ϕ`(t), t, t))

i(t)*T = J*(diff(diff(varphi(t), t), t))

 (2)

Isolate i(t) and taking the derivative

i(t) = J*(diff(diff(varphi(t), t), t))/T

diff(i(t), t) = J*(diff(diff(diff(varphi(t), t), t), t))/T

Task insertion doesn't work anymore....

Asked by: Regnar Andersen 25
task palette update
March 12 2023
2  0

Hi MaplePrimes,

I've updated to the 2023 version of Maple. After the update I chose to remove older version folders in Windows.

Since then I cant't use my tasks any longer. I've re created the tasks and the are also shown in the Task Palette, but clicking on a task results in nothing. I can though create a new Task and after the creation all my tasks can then be used again.

Its like Maple doesn't recognize the correct Help Database from the beginning. I've reinstalled Maple 2023 two or three times to try to reset the whole installation to something from scratch. Nothing that I do seems to produce the desired result. Does anybody out there have a solution or suggestion to a probable solution?

I don't know of any file that I could attach to exemplify my problem. It's not a math/maple problem relating directly to the maple code language. My tasks themselves work fine once inserted in a document. It's the insertion itself that's the problem.

Thanks.

Some unit questions about angles...

Q1: In the above, why can I only convert radians to radians. Or: Why does the menu "Chose unit" not offer arcdeg?

Q2: In the above, why is nothing happening when I enter arcdeg in the field "Enter Unit"?

Q3: How to change the displayed symbol for arcdeg to ° (in the attachment are failed attempts)?

why Maple 2023 return "undefined" embbeded inside ...

integration int

First issue I see in Maple 2023 integrate

Example 1

restart;
int( (e*x+d)^(3/2)*(c*x^2+a)^(3/2),x)

Example 2

restart;
int((1+x)^(3/2)*(x^2-x+1)^(3/2),x);

Example 3

restart;
int((c*x^4+b*x^2)^(3/2)/x^(3/2),x)

 

Worksheet below for 2023 and also for 2022.2 showing this did not have this problem in 2022.2. Internally for me, this cause other problem when post-processing this, that is why I found it. Any one knows what caused it?  Maple 2022.2 result is much longer, but it does have this "undefined" issue in the result.

Maple 2023 networktool installation problem...

Asked by: Anthrazit 680
windows java activation
March 10 2023
0  5

I know that this is not really a question regarding core Maple package, but I am running into problems during the installation process.

After having upgraded Maple networktools as mentioned, I am unable to run the activation program due to an error.

"Java Virtual Machine Launcher: Error: Could not create the Java Virtual Machine."

I've never had that problem before in previous versions. There was no Java installed on the (virtual) server, so I installed the latest OpenJDK to check if that solved the problem.

Unfortunately it didn't.

Any hints would be appreciated.

strange font problem with Maple 2023 on windows 10...

Asked by: nm 7930
font zoom display
March 09 2023
4  1

My main question is: How to change the font used in worksheet by Maple for 1D input from Courier to another font say times new roman? Is there a setting for this so it applies all the time?

ps. I found Can-I-Change-the-Default-Fonts-or-Style-for-Maple-Worksheets-and-Documents?language=en_US  (very hard to follow and confusing, but it seems that is only way to fix this problem now is to change the default font).

-----------------------------------------------------------------------------------------------------------------

I noticed strange font problem using Maple 2023 on windows 10. This problem does not show on Maple 2022.2 (at least I do not think I've seen it or noticed it before). 

Variables with _ between the names, will have the underscore not display sometimes as I move the cursor around (movie at end).

When scrolling back up, the underscores no longer become visible. 

But as I move the cursor over the variable name which containes the underscore, they will now show up.

I am sure this is a font issue. The zoom is set at 100%. I made no changes at all other than making the input 1D math as I normally do and set the default to worksheet. Some of my setting are below.

This could be a DPI issue settings of some sort. My monitor is standard monitor (not a 4K one) and again, I have not changed any settings on my PC after I installed Maple 2023 and did not change any hardware.
