u
To store a parametric function
*

○ ○ ○ ○ ○
Example
To store the following functions in memory areas Xt3 and Yt3 :
x
= 3 sin T
y
= 3 cos T
3
(TYPE)
d
(Param) (Specifies parametric expression.)
d
svw
(Inputs and stores
x
expression.)
d
cvw
(Inputs and stores
y
expression.)
u
To store an X = constant expression
*

○ ○ ○ ○ ○
Example
To store the following expression in memory area X4 :
X = 3
3
(TYPE)
e
(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.
u
To store an inequality

○ ○ ○ ○ ○
Example
To store the following inequality in memory area Y5 :

x

– 2
x
– 6

(TYPE)
f
(INEQUA)
b
(Y>) (Specifies an inequality.)
vx
-c
v
-g
(Inputs expression.)
w
(Stores expression.)

1
You will not be able to store the expression in
an area that already contains a rectangular
coordinate expression, polar coordinate
expression, X = constant expression or
inequality. Select another area to store your
expression or delete the existing expression
first.
*
2
A function cannot be stored into a memory area
that already contains a function of a different type
from the one you are trying to store. Select a
memory area that contains a function that is the
same type as the one you are storing, or delete
the function in the memory area to which you are
trying to store.
