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.
-- Keyword: additive If declare(f,additive)
has been executed, then:
(1) If f
is univariate, whenever the simplifier encounters f
applied to a sum, f
will be distributed over that sum. I.e. f(y+x)
will simplify to f(y)+f(x)
.
(2) If f
is a function of 2 or more arguments, additivity is defined as additivity in the first argument to f
, as in the case of sum
or integrate
, i.e. f(h(x)+g(x),x)
will simplify to f(h(x),x)+f(g(x),x)
. This simplification does not occur when f
is applied to expressions of the form sum(x[i],i,lower-limit,upper-limit)
.
