Hi,

I'm working on formatting my tables for export to PDF. Is there a way to align the text in the cells (to the left, for example)?

Thanks

I do not understand why select(has,-a^2,x); returns 1 but select(has,a^2,x); returned undefined.

Should not both return undefined, since there is no x anywhere in the expression?

I looked at help and do not see a clue so far.

Here is another variation, where I changed a^2 to a

The good thing is that has(C,x) returns false in both case. So the problem is not with the has call. It is select which decided to return 1 when there is negative sign. But why?

Trying to use plot to connect a series of points for illustrative purposes, but the functionality seems to have broken in 2024 or else I'm overlooking something. Related/unrelated: When I copy the related code from the cell and paste it into another application (like a browser) the list of points is reversed: e.g. `

plot({[-1, -2], [-1, 1], [-1, 6], [3, -2], [3, 6]}, x = -3 .. 4, y = -4 .. 10, style = line)` 

(That was literally me copy and pasting the relevant code from Maple into this form.)

The plot in question can be seen below. Also to note, if I leave off the last [3,-2] point, it will correctly plot the graph. It's ony when I add in that last point that I suddenly get the shape I do below. 

In 1-D Math, subscripts can be found with crtl-F

In 2-D Math this does not work. 

Also powers of (^) cannot be searched in 2D-Math.

Are there any ways to perfom searches on subscripts or superscripts in 2-D Math?

i did plot without reducing the decimal but when i reduce to 2 decimal this error is showing up How i fix this issue?

Looking back at this question:

https://www.mapleprimes.com/questions/37691-How-Do-I-Change-The-Background-Colour

the reply by Hmm in 2009

"In Linux there is an X11 resource file for the classic worksheet, one of the settings controls the background color.  The distributed file is located in the maple/X11_defaults directory."

suggested a solution only thiis does not work for me in Maple2024. Perhaps because this worked for the classic view.

Why is there still no way to do this after 16 years or perhaps I just cannot find the option?

Is there away to change the background colour or even invert all colours?

I occasionally find myself inexplicably in a region of my worksheet that does not respond to my editing, fe.g., I cannot erae or I cannot copy. I recently typed a command-there was an error of some form and I tried unsuccessfully to edit it. Then I tried to copy the code and enter it at a prompt. It refused to enter it at the prompt but copied it below the prompt in a strnge region that I do not understand. When I retyped the command at a prompt it worked fine. I do not understand th dead regions that pop up mysteriously. (I am using Maple 2024 on a Mac) The page is too long to copy but I could upload it if given directions.

in this equation we have a list of a lot paramter which i have to find it but in prgress to find it some issue are appear i don't know how many term i have to replacing by algsubs there is any way for showing that something like lpring just for factoring and replacing if we did something like that in one step we can replacing all and then find our parameter there is any way for finding parameter like that?

in this integral PDE author did a substitution and the integral is simplify and removing how i can do that as mention in picture i did try but i think need a technique

All three expressions define the same initial velocity condition in different notations.
ic1 := u(x, 0) = f, D[2](u)(x, 0) = g
ic2 := u(x, 0) = f, diff(u(x, 0), t) = g;
ic3 := u(x, 0) = f, u__t(x, 0) = g;  

Why does only ic1 work while ic2 and ic3 do not? Should I use another way?

Working on updating a very large and out of date guidebook and I need the content of execution cells to be 'Text' for illustrative purposes. It's tedious to constantly have to hit F5 for every, single, new, cell as I'm working through this. Is there a way I can just have the default style be 'Text' instead of 'Math'?  I can't seem to find that as an option anywhere.

Ctrl-j/k work fine for inserting a new execution prompt, why doesn't there seem to be a short cut for a new text prompt?  Ctrl+shift+j/k just enters a new line in the current execution prompt.  I'm on Linux using Maplesoft 2024.

I'm doing something wrong again in the attached file. Please advise.
