Question about CAS and Graphing

[Mysilmaril]

Thanks, but no joy.

Declaring the variable in Home eliminates the syntax error, but setting it equal to some number results in a constant plot ... For example X = 0, results in 1/2 * x^2 always = 0 ... no parabolic curve.

Too bad the app doesn't allow you to easily swap out a variable when bringing an equation over from CAS.

I guess you just have to modify the equation for the app.
