Subject: The integration test suites for Sage.
I just discovered the recent threads "An independent integration

test suite" and "The Charlwood Fifty".

I looked at the test suites as a Sage user and used the default

('maxima') algorithm.

Martin> "Maxima" to "Sympy"; perhaps somebody could explain how?

That is easy! The docs say:

integral(expression, v=None, a=None, b=None, algorithm=None)

algorithm - (default: ?maxima?) one of

?maxima? - use maxima (the default)

?sympy? - use sympy (also in Sage)

Why does FriCas not provide an interface to the selection box of

Sage's integral function?

My results are in [1]. Please let me know if you spot any errors.
