When trying to integrate:
integrate(1/(x^4+2*a*x^2+a^2-1),x)
I get a list containing "all possible solutions"; that's okay, but how
do I determine what conditions the alternatives hold for? Is there an
automated way; or do I have to evaluate each solution separately
?Dealing with the same prob
This is copy of announcement that I posted to newsgroups:
FriCAS is an advanced computer algebra system. Its capabilities
range from calculus (integration and differentiation) to abstract
algebra. It can plot functions and has integrated help system.
FriCAS 1.3.3 should build on Linux and many Un

When 'integrate' returns a list of results, there are conditions
associated with them. More specifically, it tries to ensure
(y)^(1/n) is real when n is even, aka ensure y is positive.
So in the example of 'integrate(1/(x^4+2*a*x^2+a^2-1),x)',
the first answer, (-a-1) and (-a+1) should be positiv
