Question about CAS and Graphing

RE: Question about CAS and Graphing
If you define f as a function in the CAS
(for example, by entering "f(x):=1/2*x^2") then in the Function Symbolic View entering and checking F1(X)=f(X) should also bring up a parabola in the Function plot view. There is an issue with moving nonfloatingpoint values from the CAS to the numeric (Function, Home, etc.) environment (this can be seen with the above example by going to the Function Numeric View). To ameliorate this issue you can uncheck the "Exact" setting in the CAS Settings screen. Plotting won't be as fast as F1(X)=1/2*X^2 due to the many round trips between the CAS and numeric environments.
