RE: CAS command question
Well let's continue to evaluate the CAS in separate threads
For example in this thread related to the parts of an inequality, report that the HPPRIME CAS does not perform operations with inequalities, such as simplify, other results are strange, and there was no response (x<13) AND (x>5); returns (13>x) AND (x>5) // ok the same above expression, but rewritten. 5<x<13; returns 0 ? (Inconsistency) (x<13) OR (x<5); returns (13>x) OR (5>x) // ok (x<13) XOR (x<5); returns 0? not(x<13); returns NOT(13>x) // Does not reverse inequality (2*x>4)/2; ⇨ (2*x > 4)/2; This must be the output ⇨ 2*x/2 > 4/2 ⇨ x < 2 collect( (x+13*x) > (3*x+53*x)); ⇨ (x+13*x) > (3*x+53*x) This must be the output ⇨ (x3*x)+1 > (3*x3*x)+5 ⇨ (2*x+1) > 5
