Storing a Function
This section presents a number of examples that illustrate how to store a Graph & Table
application function.
u
To store a rectangular coordinate function (Y=)
Example:
To store the rectangular coordinate function
y
= 2
x
2
– 5 in line number
y
1
(1) On the Graph Editor window, tap [Type] and then [
y
=Type] to specify a rectangular
coordinate expression.
(2) Tap the box to the right of line number “
y
1”, and then input the expression:
2x{
2-5
.
(3) Press
E
to store the expression.
u
To store a polar coordinate equation (r=)
Example:
To store the polar coordinate equation
r
= 5sin3
θ
in line number
r
2
(1) On the Graph Editor window, tap [Type] and then [
r
=Type] to specify a polar coordinate
expression.
(2) Tap the box to the right of line number “
r
2”, and then input the expression:
k
9
f
T
s
d

)
.
(3) Tap
w
to store the expression.
u
To store parametric functions
Example:
To store the parametric functions below in line numbers
xt
3/
yt
3
xt
= 3sin
t
yt
= 3cos
t
(1) On the Graph Editor window, tap [Type] and then [ParamType] to specify parametric
expressions.
(2) Tap the box to the right of line number “
xt
3”, and then input the
x
-expression:
k
