Storing Values and Equations• Store a value by entering a value, pressing
, then and whatever letter you’d like to use.
• Access Y1 with– To substitute into a stored equation (in Y= menu),
use function notation: Y1(15) will substitute 15 into the equation in Y1. Y1(A) will substitute the stored value for “A” into Y1.
– store an equation from a regression
