HP Prime: =f(x):=expression in spreadsheet app « Next Oldest | Next Newest »

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.

Here are a couple of things that you can do: - Enter A1 as =Spreadsheet.A2*SIN(X) - Enter A2 as 1 - in command line type: Function.F1:=A2(1) - go to function app, you can draw your function. cyrille
