Hi,

I also noticed these problems.

I initially thought it was because I was using MF through wine in a linux workstation but I tested it in another lab with MF installed in a Windows 10 and the problems were still there.

I will try to send the issue through my university tech support but meanwhile, the build # is 1880208.

Hi, @acer .

Thanks for the suggestion. Starting with your suggestion, I wrote Pi*x*I and I:=1i, since MapleFlow didn't recognized I alone as imaginary, and it worked. Then I entered (Pi*x*1I) and (Pi*x)i, no space, and they both worked.

Regarding the convertion to trigonometric form, in the same way, worked but doesn't! Interesting! It looks like the MapleFlow engine needs a number before the i or I to recognize it as imaginary.

hi, @nm .

Thanks for the prompt reply.

Neither solutions worked in MapleFlow; the plot still gives me the same message.

hi, @Kitonum .

thanks for the promptly reply! I didn´t think about that!

Hi, @Carl Love 

I see your point; hadn't considered that! Thanks very much.

Thanks very much, @Carl Love 

It worked just as I wanted!

Hi, @Carl Love 

Thanks for the quickly reply!

Sorry but I wasn´t clear on what I was trying to accomplish. What I'm looking for is to do a multiple assignment using the piecewise expression, like (just an example) a regular multiple assignment,

but extended to the piecewise expression:

such that, if c < d, e = a and f = 2*b or, if c >= d, e = 3*a and f = b.

It looks like I got more questions!!

How could I do multiple assignments in the following form?

Hi, @Carl Love.

Thanks for the promptly reply!

It works now!!

Hi, @Samir Khan.

One more question: why this one doesn't work:

a:=6

b:=5

c:=4

d := ifelse(a > b, (ifelse a>c, a, c), b)

Hi, @Samir Khan.

Thanks for the quickly reply.

I have use for both of your suggestions! Thanks very much.

Hi, @acer.

I tried that but it didn´t work. Stilll the same...

I cannot check the installation/re-install because it is installed in the university lab and I'm not in charge of it!

Hi, Samir.

I watched the Seminar this morning and it was very useful. Thanks vry much.

You mentioned in the seminar that MapleFlow suports most of the packages Maple support, but mainly those most used by designers. So, I'd like to suggest if MapleFlow could (in future versions) also support a few more palletes, like Calculus, Common Symbols and Constants and Symbols.

Best regards

Hi,@Preben Alsholm , @acer.

Really strange! Even if I don´t use any initialization file, I still got the same problems.

hi, @acer.

Sure, no problem.

And no, there is no code in the Startup region of the worksheets nor any hidden inputs. I initially didn´t attached the worksheets because I've got them directly from Maple website. But they're attached now, along with my "C:\Users\charliec\maple.ini" file (I had to rename it in order to upload it!)
