CHECK Checks—that is, selects—the Symbolic view variable Symbn.
Symbn can be any of the following:
• F0-F9—for the Function app
• E0-E9—for the Solve app
• H1-H5—for the Statistics 1Var app
• S1-S5—for the Statistics 2Var app
• X0/Y0-X9/Y9—for the parametric app
• R0-R9—for the Polar app
• U0-U9—for the Sequence app
CHECK(Symbn)
Example:
CHECK(F1) checks the Function app Symbolic view variable
F1. The result is that F1(X) is drawn in the Plot view and has a
column of function values in the Numeric view of the Function
app.
UNCHECK Unchecks the Symbolic view variable Symbn.
UNCHECK(Symbn)
Example:
UNCHECK(R1) unchecks the Polar app Symbolic view
variable R1. The result is that R1() is not drawn in the Plot
view and does not appear in the Numeric view of the Polar
app.
