I do not use input 2D math in document mode. But was trying it now to see if I can enter this to check my hand solution
In worksheet, this is what I do
But I do not know how to enter if possible, in document mode 2D math. THis is what I tried. Created document mode. Picked the DEL operator from the left side common symbols window. But I do not know how to do the rest.
Clearly I am doing something silly. This is why I prefer plain Maple code, becuase I can see what I am typing :)
But was wondering, how to do the above in docuemnt mode + 2D math? To make it look close to how it shows in the book. Does one need special palette for this?
