Adding more utility functions to the calculus functional.py file

[ParamThakkar123]

Problem Description

I think that there should be extra utility functions for calculus

Proposed Solution

We can add more utility functions in calculus in the functional.py file for more features and functions that we can use for mathematics

Alternatives Considered

I have added 3 utility functions to the functional.py file

Additional Information

No response

Is there an existing issue for this?

• [X] I have searched the existing issues for a bug report that matches the one I want to file, without success.

Hi @ParamThakkar123! I do not see the need for these functions. Can you explain how this might improve the user experience? For example, I do not see any difference between the existing function taylor and your proposed taylor_terms.

Two other things:

• I'd advise to first open the issue and ask for comments - possibly first ask on sage-support if you are not sure whether some functionality might be useful for others.
• If you want that a pull request shows up on the issue, you have to write fixes #issue_number instead of solves #issue_number. For some reason, github does not recognize the latter.

Hello @mantepse , Actually the functions that I have added would make the not the user experience better but the user accessibility. User can have access to more utility functions to perform on a particular function.

I don't understand. What is the difference between your proposed taylor_terms function and the function taylor?

[ParamThakkar123]

They were the same. I didn't notice the difference. Sorry for that. I have removed the taylor_terms functions and pushed the changes in my PR #37059

As far as I can tell, the same is true for the other two functions.
