Thanks guys:
 
I do not know why everything seems so complicated. Excuse me.
There is a written guide on how to proceed?
I read the link http://www.mapleprimes.com/book/posting2dmathmapleprimes

And I made a comment using the WordPad, but I'm still not pleased with the outcome.

Gracias

1. how to replace in the expression:

θ+e^(-(η s)/(l c m) t) ((c m T_0+c_1 m_1 T_1)/(c m +c_1 m_1 ))-θ

the product of c * m * l by:

c m +c_1 m_1

so that I get the following expression:

θ+e^(-(η s)/(l (c m +c_1 m_1)) t) ((c m T_0+c_1 m_1 T_1)/(c m +c_1 m_1 ))-θ

have used subs and algsubs. And I have failed. I had to do it manually.
 
2. I obteniedo the following outputs of the units:

Unit(W),  Unit(s), Unit(degC)

 I would like to display in format 2-D Math

3. In expressing the values of the parameters in their units and graph the function I get the following error
 
plot([Ca(t), Cb(t)], t = 0 .. 10, color = [red, blue], style = [point, line], useunits)
 

Warning, unable to evaluate the functions to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correct

Some orientation
Gracias.

work with literal subscript. desire to isolate theta [B]. I show in the pdf file what the steps in Malpas and their outputs. With the last option Maple returns nothing.Download 9494_Literal Subscripts 1.pdf

How come?

You can see in http://www.maplesoft.com/applications/view.aspx?SID=4515

By running the commands:

LibraryTools:-Create("I:.\\ITS90.mla"); libname := "I:\\Maple WorkSheets's Hermes", libname;

savelib(ITS90)

The only information that is in the worksheet is:

module( ) local A,B,C,Q Export Wr,T90,dTdw dWdt; end module

It's like if you lost the source code.

How to keep it for future arrangements?

From the MLA can be recovered? . 

Gracias Hermes

Acer,

As you say the right thing is to save as mla.

My problem as I hope you can see in the PDF, is that within the module two different procedures, using the same matrix values. I would find a way to avoid having to testify in each case a local array. And declare such arrays within the module in which the procedures are.

I need your comments,
I often get a spread of about 4438 Hz, in analyzing the datos.Y got a range. What is wrong? It is the wrong approach?
