@acer 

The code works, but since I'm using Notepad, I'm not sure how to plot graphs with this data. I plan to try another approach. Do you have any ideas about graphing this data?

@acer 

I tried using other file locations, but it gave me an error. So, I left it empty, and when it’s empty, the file is added next to the Maple worksheet file (maple.mw). You should find the file beside the worksheet. Also is text i want axcel file,  If you want to add a place for a file desktop is good.

i did truly is not my first time...

@janhardo I think MaplePrimes has several moderators, each with their own policies. For example, Acer mentioned in a branch post that I wouldn’t face any issues and that no one would delete it. However, I’ve tried posting four times, and it still gets deleted every time.

i will do bro but i praper another quest...

@mmcdara thanks a lot i reply this but i think you are out of mood to find emazing solution 

i did that but again delete it...

@acer I’ve tried this multiple times, but it doesn’t make a difference. It seems that moderators simply review certain topics and delete them. It feels like if you want to ask a new question, you’re required to delete a similar one, which doesn’t make much sense.

i don't know which moderator delete it !...

@mmcdara  Thank God for your help! I’ve been working on this method since last night, trying to figure it out on my own so I wouldn’t feel embarrassed asking here. I’m amazed that you managed to do this in just half an hour! However, I’m very cautious about making a mistake with an equation that hasn’t been solved before. That’s why I need to ask every possible question. My plan is to solve this one first, and then tackle an unsolved equation. Do you think this formula can be applied to other equations as well? And you are using codes that I have never seen before, which is strange to me

genral.mw

i try but fail for other

Thanks, but not working...

@mmcdara  is seems is so good your code you give it range and i don't know why not apply and give me error when i transfer latex code but the issue is like that

also the code of @accer is work but th equation  must have the similar factor then it work but if this is work it will be so emazing i did this mistake in my paper at least 8 of them have same issue and editor of journal IF 5.4 give me reject becuase of that
By your code i get the whole idea of Hirota bilinear i work on it to get better then i will write some extra notation if help me  it will be emazing becuase i get full notion of hirota right now, by your coding i can finish hirota.

i post another question to get bilinear ...

`There is no more prime differentiation variable; all derivatives will be displayed as indexed functions`

I have changed a and b to A and B, because if you are going to set a value for a[1] then a becomes a table and should not be used as a separate variable. You might get away with it but it is bad practice.
I'm going to stop using the =0 on the rhs, because it simplifies many of the manipulations required.
