How to know which Maple command automatically maps on list entries or not?

In Mathematica, almost all commands automatically thread (or map) over a list. In Maple, how does one determine which command automatically acts over entries of a list or a set? For example: y+p*x=2*sqrt(x*y); r:=[solve(%,y)]; This gives list of…

How can I programatically truncate order "O" terms in Maple?

In Maple, taylor(exp(x),x,2); returns 1+x+O(x2). How can I automatically convert this result to the same expression with the O(x2) terms removed? I.e. something like removeBigO(taylor(exp(x),x,2)); to return 1+x?"

How to convert a Maple expression x*y to Matlab for the result x.*y?

A Maple expression (for example, x^3+x*y) can be converted to Matlab by with(CodeGeneration): Matlab(x^3+x*y); However, in Matlab, there are two kinds of product: A*B and A.*B. The above way will give x^3+x*y. Is there a convenient way to get the…
