## How to isolate terms in expression...

Maple 15

For example, I have the expression:

f:=sin(i*Pi/2)+cos(i*Pi/4)+i+A[i]*cos(i*6)+5*ln(5*r)*Pi+5+x;

How to isolate terms in i and other terms (automatically) to get :

f1:=sin(i*Pi/2)+cos(i*Pi/4)+i+A[i]*cos(i*6);

f2:=5*ln(5*r)*Pi+5+x;

## Maple analog to Mathematica's Manipulate...

Maple 15

Hi,

I have explored some multi-animation with maple, but I can not change the parameters one by one.

http://www.mapleprimes.com/questions/99833-Procedure-For-ANIMATE-Multiparametrique

Command Explore is analog to Mathematica's Manipulate but the problem in a new worksheet.

How to get Explore like Manipulate in the same worksheet ?

## Exploration Assistant...

Maple 15

Hi,

I want to explore for example:

Explore(plot(Sum(i^2*sin(i*x), i = 1 .. n), x = 0 .. 10));

I know that animate can be applied as:

animate(plot, [Sum(i^2*sin(i*x), i = 1 .. n), x = 0 .. 10], n = 1 .. 10);

Is it possible to get the Exploration Assistant in the same worksheet after the command Explore and not in another worksheet ?

Explore can be done for many parameters which is not the case for animate.

Thanks for any suggestion

## Manipulating equations...

Maple 15

Hi all,

For example, I have this equation:

restart: eq:=diff(theta(t),t)*y(theta(t))+x(t)=sin(x(t));

and

wm:=diff(theta(t),t);

I want to replace in eq, wm:=diff(theta(t),t). I used commands eval, subs as:

subs(diff(theta(t),t)=wm,eq);

eval(eq,diff(theta(t),t)=wm);

but with no result

Thanks for any suggestion

## with(OrthogonalExpansions)...

Hi,

with(OrthogonalExpansions) not working in Maple 15 (work in Maple 14). What is the equivalent package for FourierSeries calculations?
