Example To store the following expressions in memory areas Xt3 and Yt3:
x = 3 sinT
y = 3 cosT

u
To create a composite function
Example To use relations in Y1 and Y2 to create composite functions for Y3
and Y4
Y1 = (
x
+ 1), Y2 =
x 2
+ 3
Assign Y1°Y2 to Y3, and Y2°Y1 to Y4.
(Y1°Y2 = ((
x
2 + 3) +1) = (
x
2 + 4) Y2°Y1 = ( (
x
+ 1)) 2 + 3 =
x
+ 4 (
x >
−1))
Input relations into Y3 and Y4.
