A while back, I was lurking on these forums and I came across this thread:
I attempted to integrate dx /(1+x^16) like Mr. von Cube did with his NSpire. However, I used my 50g.
I am almost POSITIVE that I got an answer (Lots of ln and atan terms.)
However, I tried again recently, and I got an INTVX (or RISCH) error:
Unable to factor.
This really isn't terribly important; it just bothers me!
Any ideas as to why it may have worked back then but doesn't now?
Most likely one of the following:
1) Insufficient memory. Free a respectable quantity, then try again.
2) Hitting some limit on the number of factors or length of the answer. See parameter settings.
3) Hitting some limit in the depth of factoring. See parameter settings.
If the above doesn't help, try changing the exponent 16 to 2, then 4, then 8, then 16, and see where it fails.
