Newbie: problem solving basic equations



Good day,

I know when something *could* be done and is not being done. I know when 
something is not being done for good reasons. The examples I gave were 
problems Maxima has to be able to solve. So far, I've learned that half 
of the could be solved using the right settings.

We are left with the other half. Why is it that other Computer Systems 
can solve these and not Maxima? Well, I'm looking at it right now, 
trying to figure out if I can go from 50% to 100% the same way I went 
from 0% to 50%.

There is no way I will accept having to factor and expand stuff. I use 
Computer Algebra to save time, not waste it. Other packages are beyond 
that now. Maxima has to match (in some way) the abilities of the other 
packages. Unfortunately, I'm not an algebra specialist and I cannot be 
expected to expand  Maxima.

It is.

I'm very much a Mathcad user and it is very frustrating. Not to mention 
that it is a proprietary solution and I don't think my (freely 
available, publishable, reproducible) research should be based on 
proprietary software.

Some think for teaching. I would feel much better teaching a course 
using free (as in "open source") software rather than feeding some 
marketing hype.


So far though, Maxima has shown itself to be even more frustrating (what is it with the evil user interface?).


I'm ready to cope with this just to see if it is a learning curve thing 
or if Maxima is really frustrating.
