A result of a calculation I was doing generated this expression....
q-q Exp[-a x] + c Exp[-a x]
naturally my next step was Simplify and I thought I'd get the Exp[- ax]
collected.....to my complete surprize I got the following:
Exp[-a x] (c + (-1+ Exp[a x]) q
How on Earth did Mathematica come up with this? I checked FullSimplify
which did collect Exp[-a x]....
On re-reading my question before I submitted it, I see that with
Simplify Mathematica 'collected' using Exp[- a x] q.....of course,
visually this expression seems quite complex and would seem to take much
more 'thinking' to get ......why do Simplify and FullSimplify have such
a vast difference in what is considered 'Simpler'?
