Results
variables
The Function, Statistics 1Var, Statistics 2Var, and Inference
apps offer functions that generate results that can be re-
used outside those apps (such as in a program). For
example, the Function app can find a root of a function,
and that root is written to a variable called Root. That
variable can then be used elsewhere.
The results variables are listed with the apps that generate
them. See “App variables” on page 221.
