## Using convert command in desired manner....

This question is somewhat related to my question
http://mapleprimes.com/questions/219357-How-To-Use-ToJet-Command-When-Differential
I am trying every possible way that I learned so far but not getting desired result.

## How to write composite differentiation i...

Dear Sir

I am performing compositing differetiation of some function and need to compsite derivatives in subscript format without using 'D'. Please see worksheet.

Is possible to display as etc.

## I am sorry ................

Actually I did those chnages but forget to save the editings before uploading to Mapleprime. Thank you very much for you efforts.

## Surprising !!!!...

The thing that I was doing wrong is only 'I' as complex number in place of 'i'.  Now everything is working fine.
But please see why this symbol 'j' as complex number not creating problem in direct computation ?

Thanks a lot.

## That this a function.........

Here g(u[x]) is actually a function of u[x] and g[u[x]] is derivative of g with respect to u[x].

## Useful !!! but...........

Since my PDE involves function f(u) so removing 'integrabilityconditions = false' is not a better option neigther the "casesplit(DetSys)' solves my purpose of obtaining contraint differential equation for f(u). Anyway 'RosenfeldGroebner' worked for me.

## No matter what other say..............

No matter what other say, he is a pure Russian by heart. What peoples can expect from him any further !!! He has opened almost new field to mathematicians and he left peoples scratching heads for another century just like Poicare did. Let him enjoy his life.

## Stack Exchange Would appropriate...

I think this community is not suitable for asking such questions. You can ask such type of  questions on StackExchange.

## This question is slightly different...

See Top answer to my question by Preben Alsholm you will see how simple answer he has given. That is exactly I was looking for. More elaborate answer is also given by Carl Love.

## Frontend is great option...

@PascalQM Thanks for your help but solution to my problem is better handled with "frontend", see answer given by Prebem Alsholm.

## Exactly...........!!!!!!...

@Preben Alsholm That the way I am looking for. How this frontend works in general way ? Because I have seen it in Maple help but could not understand its real use.

## Sub will do but..............

That will do but do not want to do in this way. I am looking for alternative and more flexible option so that I can find coefficient in single command line.

## Nailing habit !...

I must say you use to nail every query.

## Color change on exporting...

When I export plot in png format by right clicking on plot why color of plot slightly changes ?
