Online Algebra Calculator
Many of users do not use powerful Maxima computer algebra system for systematic work, but for ad hoc algebraic calculations – equations, functions, matrixes, etc. only. To do this job, it is not useful to download the whole application from a web site.
-- Option variable: inflag Default value: false
When inflag is true, functions for part extraction inspect the internal form of expr.
Note that the simplifier re-orders expressions. Thus first (x + y) returns x if inflag is true and y if inflag is false. (first (y + x) gives the same results.)
Also, setting inflag to true and calling part or substpart is the same as calling inpart or substinpart.
Functions affected by the setting of inflag are: part, substpart, first, rest, last, length, the for ... in construct, map, fullmap, maplist, reveal and pickapart.
