Graph Function Operations
uuuuu
To store an X = constant expression
Example To store the following expression in memory area X4 :
X = 3
3 (TYPE) 4 (X = c)
(Specifies X = constant expression.)
d
(Inputs expression.)
w
(Stores expression.)
• Inputting X, Y, T, r , or
θ
for the constant in the above procedures causes an error
(Syn ERROR).
uuuuu
To store an inequality
Example To store the following inequality in memory area Y5 :
y > x 2 – 2 x – 6
3 (TYPE) 6 (
g
) 1 (Y>)
(Specifies an inequality.)
vx-cv-g
(Inputs expression.)
w
(Stores expression.)
k k k k k Editing Functions in Memory
uuuuu
To edit a function in memory
Example To change the expression in memory area Y1 from y = 2 x 2 – 5
to y = 2 x 2 – 3
e
(Displays cursor.)
eeeed
(Changes contents.)
w
(Stores new graph function.)
