RE: [Request] Control of algebraic expressions CAS
expressions rewrite alters the domains of expressions in many cases, rewrite the expressions is difficult to identify entry
fabulous if you can include a flag, so that the entries are not evaluated, at least in xcas for example I want to know what the numerator and denominator of the following expression 'x^3/x^2', to make a symbolic derivation step as didactic project from my university, unfortunately this is evaluated as X =( the following code will never be executed, the CAS hpprime is good, but does not allow me to do I want, with simple improvements could be the best CAS on calculators, the hp48/50 calculator retains the inputs to run obj-> that is similar to PART function (see PART FUNCTION on HP48/50) http://www.hpmuseum.org/forum/thread-6377.html) if (operator=="/") then Return (part2*diff_table(part1,var)-part1*diff_table(part2,var))/(part2^2); end; ∂(x^3/x^2,x) -> ((x^2*∂(x^3,x))-(x^3*∂(x^2,x)))/x^2^2 -> 1 Code: |
