RE: CAS command question
About MatLab, start as a numerical engine, then business the symbolic engine of MAPLE, then buy MuPAD, Now we say that MatLab has two numerical and symbolic motors, for this reason it is already considered a CAS.
continuing with the inequations, I want to get the next result x < 2 or 2 > x, but without using solve cmd I tried collect, expand, simplify and nothing, The ti89 if simplify, I do not know if other CASs (2*x) > 4; Ans/2; ⇨ ((2*x) > 4)/2 simplify(Ans); ⇨ ((2*x) > 4)/2 // =( collect(Ans), ⇨ ((2*x) > 4)/2 // =( expand(Ans) ⇨ (1/2)*((4)>(2*x)) // =( Someone please, to prove the simplification of the previous inequalities in other CAS.
