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)
3
(Parm) (Specifies parametric expression.)
d svw
(Inputs and stores
x
expression.)
d cvw
(Inputs and stores
y
expression.)
• 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.

To store an X = constant expression
Example To store the following expression in memory area X4 :
X = 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.
