Restrictions of useThe tool that we use to solve the system is interval analysis that imposes some restrictions, not on the mathematical functions that appear in the expressions but on the way we handle their definition domain.
Assume for example that one of the expressions is:
The interval evaluation of We will get the same problem for the following examples:
There are means to deal with this problem but they are not available in the current solver. However you may still submit your system and if you have provided a valid email we will contact you after having dealt with your problem.
