I've tried changing typesetting from extended to standard, but nothing seems to work.  I got myself in some mode I cannot get out of.  I've restarted maple, and even rebooted.
 

restart

interface(typesetting = standard)

interface(typesetting = false)

Error, (in interface) typesetting must be a string of extended or standard

 

eq1 := I1 = v1/xp

Typesetting:-mprintslash([(eq1 := I1 = v1/xp)],[I1 = v1/xp])

 

NULL

NULL

x := 2

Typesetting:-mprintslash([(x := 2)],[2])

here's a snapshot because the uploaded maple document looks  weird:

I do not understandwhat this result from Maple means.

I don't know what it means when a result has "Root of", and in this case, there is also a big summation sign for which I can't tell if the variables underneath it are part of the summartion, or what.  I'd appreciate any guidance to make sense of what this means..

given :

Zin := ((Rsp + (omega*L2 - omega02^2*L2/omega)*I)*(Rpp + (omega*L1 - omega01^2*L1/omega)*I) + 0.01*omega^2*L1*L2)/(Rsp + (omega*L2 - omega02^2*L2/omega)*I)

how do I get Maple to cancel out the common term, and simplify this equation into:

Zin := Rpp + (omega*L1 - omega01^2*L1/omega)*I + (0.01*omega^2*L1*L2)/(Rsp + 
(omega*L2 - omega02^2*L2/omega)*I)

Why doesn't Maple do this automatically with something like simplify or some other command?

Thank you!

I am trying to install Syrup in my home computer (I have it installed in my work computer).  I followed the instructions in the Readme file: 

From Standard Maple:
    Open the file Syrup-Installer.mla.
    To do so, use File -> Open, choose file type 
    "Maple Library Archive (.mla)", select the file, and
    click "Open".

Everything seemed to work and the help page opened up:  But, it is not the syrup help page.  furthermore, when I type ?Syrup, it doesn't open it either.

 

When I try to run a worksheet that uses Syrup (that works on my work computer), I get these errors:

I"m going to reboot now and try again.

I don't understand where the the csgn(L) comes from in the solution below:

all the variables are defined as real:

Thanks in advance for any help.
