Hi *,
Is the following a case of total simplification failure (a certain
bug from the user's point... unless AXIOM is not targeted for
Martians who as known have no need in simplification whatsoever :)
or
it is still possible to get %pi out of the lengthy expression
%i*log(-%i) - %i*log(%i)
?
Given my previous posting about complexForm, I mean maybe just a way
to expel those nasty logarithms and see the real and imaginary parts
not intertwined rather than a correct answer.
Any, maybe even a very cumbersome way?
.....................................................................
-> simplify(%i*log(-%i) - %i*log(%i))
%i log(- %i) - %i log( %i)
-> normalize(%i*log(-%i) - %i*log(%i))
%i log(- %i) - %i log( %i)
-> complexNormalize(%i*log(-%i) - %i*log(%i))
%i log(- %i) - %i log( %i)
.....................................................................
Much thanks for any help in advance.
Best,
Vladimir
