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.)
BQTU(Inputs and stores x expression.)
BATU(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.

• A composite function can consist of up to five functions.
S To assign values to the coefficients and variables of a graph function
Example To assign the values −1, 0, and 1 to variable A in Y = AX 2 −1, and draw a
graph for each value
