I can't see your equations but look at the help page on geom3d.
Use a semilcolon with equals to assign values.
An alternate way although slightly unconventional, but we end up with the proper sequence
seq(op([1/j, -1/(2*j)^2]), j = 1 .. 10, 2)
1, -1/4, 1/3, -1/36, 1/5, -1/100, 1/7, -1/196, 1/9, -1/324
What about just nops?
There may be some discrepancies
If you wanted to force a new line on your own before getting to the end of the screen shift+enter would also continue the command.
This is the best way to view just the titles.
**edit added** ah yes, nevermind, I see you found it by clicking on the Recent button which I've never noticed. I generally just type in the location above in the address bar and go directly to the list. I rarely ever use the mapleprimes home page if ever.
[seq(add(a[ .. i]), i = 1 .. nops(a))]
[ 1, 3, 6, 10]
Maple 2016.1a is now available at the Maplesoft website that fixes this issue.
Ok finally I managed to reproduce what you might be experiencing.
The issue has to do with using the greek letter Pi and then using the wordPi.
going back deleting Pi and replacing it with ∏ or 2*∏ then again going back deleting and replacing it with Pi.
That's what I've been able to find.
My x^2 issue I found was just bad syntax there is no problem there. Your plot issue was just you putting the wrong variable to the range.
I can not replicate any errors you produce. Have been able to replicate the errors on another worksheet? Are you using windows 10? or Mac?
It seems that error only comes up when you use the greek letter from the pallete and used without the multiplication sign.
After which no matter what you do the error won't go away until you restart and use the pallete symbol with a space as multiplication again.
You aren't explaining EXACTLY what you are doing. I think you are missing some things in explaining what you are doing.
The only lines causing errors are the ones that look like this after copying to notepad
(∫)^(2 )(x)^(2) ⅆx
Your other lines that execute properly look proper when copied to notepad. I can only think you are doing some kind of deleting or adding a space or something in the wrong spot however which I can not duplicate.
After re-installing. I am having no luck (or good luck as the case may be) trying to recreate the errors you experience.
I can not, no matter what I do get the errors you see. I am trying to find out what you are doing.
