limit(erf(2*x+b),x=%plusInfinity) works fine, returning 1 as it should. Similarly, limit(erf(-2*x+b),x=%plusInfinity) works. However limit(erf(a*x+b),x=%plusInfinity) returns "failed", perhaps because FriCAS does not know if a is positive or negative. I tried to declare a:PositiveInteger, but that leads to an error " a is declared as being in PositiveInteger but has not been given a value".
Is there a way to tell FriCAS that for example a>0 so that the limit can be computed?
