Most likely the convert-to-polar route will have problems because simplify/polar does not currently handle assumptions, see this thread.

Yes, Maple is frequently not the best option for algebraic manipulations.

This time, I could download the document. Just browsing it I see, in regards to point 2, that units are displayed fine here, i.e. between double brackets. So, it seems a configuration dependent issue.

The items 2 and 3 may depend on details of your worksheet. However, a problem occurs as I get an error from its download link.

Better use a plain text editor, instead of a wordprocessor like WordPad.

The key to the use of subs is identify the syntactical parts of the expression. Note also that the exponential function is exp. You can do it e.g. by:

`θ`+exp(-(`η`* s)/(l* c* m)* t) ((c* m *T_0+c_1* m_1* T_1)/
(c* m+c_1* m_1 ))-`θ`:

subs( t= t*(l* c* m)/(c*m+c_1*m_1),%);


(exp(-eta*s*t/(c*m+c_1*m_1)))((c*m*T_0+c_1*m_1*T_1)/(c*m+c_1*m_1))

In recent days, the MapleNet version of the uploaded worksheets (like following the link View 9494_Café 1 y 2 Units.mw on MapleNet ) is not working, producing messages like "Maple Worksheet - Error ".

This worksheet is long, and I have inspected just the first few lines. But here some issues appear already.

You have fixed the value of some constants, so that M:=AM*exp(I*phi) becomes sqrt(2). Then you wrote:

alpha2:=s->-(M(s+2*Gamma)+1/2*Omega^2):

beta1:=s->-(conjugate(M)(s+2*Gamma)+1/2*Omega^2):

But as it stands, this is a constant function call:

M(x);
                                  1/2
                                 2

So, if you intended instead a product (like M*(s+2*Gamma) ), it would be better that you recheck your worksheet.
