Some of you may now the microsoft encyclopedia Encarta.
I have seen yesterday a demo of the new version that includes a CAS.
There are 2 front ends, one conventional and another one that looks
like a small digit computing platform (like the old TI30).
One interesting point is that it provides the solution of an equation
but also, optionnally, some tracing of the needed operations to go
from the problem to the solution, helping the user (eventually a
student) to grasp the method that has been used. I was wondering if
any such tool for tracing and providing textual explanation of the
method exist in maxima or would be difficult to write.
I was yesterday evidently dreaming that maxima replace encarta asap :-)
Thanks,
Nicolas
