To store a parametric function
Example To store the following expressions in memory areas Xt3 and Yt3:
x = 3 sinT
y = 3 cosT
(TYPE)
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
Assign Y1 ° Y2 to Y3, and Y2 ° Y1 to Y4.
(Y1 ° Y2 = ((x
Input relations into Y3 and Y4.
(TYPE)
(Y)
• A composite function can consist of up to five functions.
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
