RE: CAS command question
(01-03-2017 11:33 AM)DrD Wrote: 2. If the intent IS to return the indicated side of an expression or interval, why was it necessary to first evaluate the expression? Regarding 2, this has always been the behavior. A literal (symbolic) expression requires quotation (single quotes). These are left unevaluated. Otherwise, it is "evaluated" as is normally done when entering commands on the command line. Simple example: x:=t; x+y // returns t+y 'x+y' // returns x+y EDIT: Quote:left('x+y<4'); ==> x+y The second case uses evaluation. left(CAS(" 'x+y<4' ")) will return x+y Graph 3D | QPI | SolveSys |
