A few questions about the CAS view
I am trying to create a simple(st) example to visualize interpolation. But the CAS view seems to be a bit different.
My first two rows are giving correct results. The way row 5 works I would row 6's result expect to be "G := (2,3)".
The second thing I don't understand is why row 7 is not working, either. And I don't understand whether there is no result. (Visibility cannot be toggled for that line.)
