One solution to the lengthy expression problem is:
(c1) expand((1/x + 4 + x)^10000;
(d1) 1/x^10000 + ... + many more terms you'd be crazy to want to display
By "many more terms you'd be crazy to want to display," I literally
mean that string. Maxima's reveal can help out here.
Flip through a current J. Math. Phys or Physical Review -- how many
expressions are displayed that fill more than one line? Long
expressions are almost never good for numerical computations and
rarely convey much information.
I've been stung too many times with many screen fulls of worthless junk
scrolling by -- each time I did something I thought I wanted and later
realized that I didn't.
