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?
