• You will not be able to store the expression in an area that already contains a
parametric function. Select another area to store your expression or delete the
existing parametric function first. This also applies when storing inequalities.
u uu u uTo store a parametric function
Example To store the following functions in memory areas Xt2 and Yt2:
x = 3 sin T
y = 3 cos T
[2(Parm)
(Specifies parametric expression.)
d sTw
(Inputs and stores x expression.)
d cTw
(Inputs and stores y expression.)
• You will not be able to store the expression in an area that already contains a
rectangular coordinate expression or inequality. Select another area to store your
expression or delete the existing expression first.
u uu u uTo store an inequality
Example To store the following inequality in memory area Y3:
y > x 2 – 2 x – 6
[[1(Y>)
(Specifies an inequality.)
Tx-cT-g
(Inputs expression.)
w
(Stores expression.)
