u To store a parametric function
Example To store the following expressions in memory areas Xt3 and Yt3:
x = 3 sinT
y = 3 cosT
3(TYPE) 3(Parm) (Specifies parametric expression.)
dsvw(Inputs and stores
x expression.)
dcvw(Inputs and stores
y expression.)
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.
3(TYPE) 1(Y=) J4(GRPH)
1(Y) b(1(Y) c)w
J4(GRPH) 1(Y) c
(1(Y) b)w
• A composite function can consist of up to five functions.
u 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
