Does anybody know how to use the tools of the hp48g Equation Writer?
What is +1-1 for? Most of times, T->, <-T and <--> seem to do the same thing (but the latter is the worse). And what about the other commands?
Is there a better documentation about them?
Or are the commands so useless that nobody wrote about it?
Has this been asked before?
The manual has too few examples...
