S
To store a parametric function
Example
To store the following expressions in memory areas Xt3 and Yt3:
x
= 3 sinT
y
= 3 cosT
(TYPE)
(Parm) (Specifies parametric expression.)
B
QTU
(Inputs and stores
x
expression.)
B
ATU
(Inputs and stores
y
expression.)
S
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.
