STo 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.)

STo create a composite function

Example

To use relations in Y1 and Y2 to create composite functions for Y3

 

and Y4

 

 

Y1 = (X + 1), Y2 = X2 + 3

 

Assign Y1°Y2 to Y3, and Y2°Y1 to Y4.

 

(Y1°Y2 =2 + 3) +1) = (x2 + 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.

STo 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 = AX2−1, and draw a

 

graph for each value
