 HP Prime: =f(x):=expression in spreadsheet app - Printable Version +- HP Forums (https://archived.hpcalc.org/museumforum) +-- Forum: HP Museum Forums (https://archived.hpcalc.org/museumforum/forum-1.html) +--- Forum: Old HP Forum Archives (https://archived.hpcalc.org/museumforum/forum-2.html) +--- Thread: HP Prime: =f(x):=expression in spreadsheet app (/thread-257626.html) HP Prime: =f(x):=expression in spreadsheet app - CR Haeger - 12-04-2013 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.

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
