Hello,

Thanks to Han and others who suggested how to define an expression in f(x) then define F1 to allow it to be plotted:

f(x):=x^2-5;F1:=f;

// allows X^2-5 to be plotted in F1

The above also seems to work in two spreadsheet app cells (ie =f(x):=x^2-5) IF the expression is typed in. However, I cant figure out how to define f(x) if I REFER to an expression located in another cell. So, =f(x):=cellref does not seem to work.

Any ideas on how to do this in the spreadsheet? If so, it would be handy for plotting expressions generated in a spreadsheet.

Best,

Carl
