I hope this is not too much a trivial question, I'm a newbie to Maxima. I'd
like to rearrange expressions like this
(3*cos(d1)^3-3*cos(d2)^3)*x
or this
(3*a*b1-3*a*b2)*x
into a simpler form with collected terms;
3*(cos(d1)^3-cos(d2)^3)*x
3*a*(b1-b2)*x
Is there a solution that works in BOTH cases ?
Factor or facsum work for the 2nd expression but lead to unwanted
trigonometric expansion in the 1st expression.
It seemed to me a very simple rearrangment to do but i could not find a
solution after a long search.
Thank you very much for your help.
