I've been pulling my hair out for a couple of hours trying to
define a variable x to be positive. Online help says that typing
>> Positive[x] = True
should do it, but it doesn't work and gives a message saying
>> Set::write : Tag Positive in Positive[x] is Protected
I cleared x before trying this. I am positively flummoxed and am
in desperate need of help to save my receding hairline.
Thanks in advance,
