map(f, foldl(`*`, 1, a, b));
foldl(`*`, 1, map(f,a), map(f,b));

map(f, foldl(`+`, 0, a, b));
foldl(`+`, 0, map(f,a), map(f,b));

i discover it can auto calculate ring homomorphism, 

if i define a function f below

factor(map(f, foldl(`*`, 1, a, b))+map(f, foldl(`*`, 1, b, c))) = map(f, foldl(`*`, 1, a, c));

how to convert this f into a function with two input parameters?

 

Hello,

I have a maple code, which some expressions have more that 80000 terms and I need to double integrate them. The terms have sine, cossine trigonometric functions.

I tried to used de MAP command, it works for the first expressions but, after a while, Maple displays an error message related to too large expression.

Do you know how to handle large expressions ?

Thank you.

Hello,

I use a map() command to get the values of function for each element of vector. Here is an example of a simple task:

restart:

A:=[1,2,8];

f1:=x->2*x;
f1_table_A:=Vector([map(f1,A)]);

I would like to do the same with piecewise function but it doesn't work. Here is an example:

restart:
with(plots):
f:=2*x:
g:=x^2:

h:=x->piecewise( 0<=x and x<= 5, f, 5<x and x <= 10, g ) ;
A:=[1,2,8]:
h_table_A:=map(h,A):

Is it possible to work with piecewise function? Maybe someone has an idea how to do it in different way?

Kind regards,

Iza

Hi, 

What I want is quite simple but I have not seen it implemented anywhere yet. 

I have an explicit map F from the plane into itself. (not an ODE but simply a map) 

Then I have a set X, (something like a line segment or a rectangle in the plane) for which I 

really need to keep track of the images $F(X), F^2(X), F^3(X)$, and so on.

Is there a way to plot the image of a set in Maple? 

Thank you very much for your interests in the question. 

 

 

 

Is there a way to make the first part of this look like the second picture depicted here? Also after intigration is there a way to make the highlighted posrtion not have an "ln(e)" parts and just have the exponetials and there constants?

Obviously I dont want to have to manually input this section everytime, is there some command I can use to achieve this goal?

Above is the outcome I am getting at the current time... and I used map(expand,...) to do the expansion then simplifing it goes back to the origional. 

Below is the outcome I would like to achieve...you can see that this is a different method. The problem I have is this is the right click method of expansion and I am tring to build a program that solves matrix ODE's by just inputing the initial matrix and it doing everything so i can check my answers step by step. 

So my question is, is there another method of command input to get the bottom line in the below picture?
