Casio FX-CG20 AU - To Create a Composite Function; To Store a Parametric Function

5-14
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(Param) (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(GRAPH)

• A composite function can consist of up to five functions.
