Hello everyone, I have some weird problems with the maple. The problems are different for the document mode and the worksheet mode, however I strongly believe that they are connected. Starting with the document mode:
I simply cannot execute any command with the symbolic notation. As you can see below, I can execute basic mathematical calculations but I can't do any symbolic math.
On the other hand, I can execute all the commands in the worksheet mode. For example check the screenshot.
However, when I try to save that file in the worksheet mode, I get this error:
And, when I close the file and re-open again, I find all the stuff I wrote in the "math mode" disappeared
