uTo 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.)

uTo create a composite function

Example	To use relations in Y1 and Y2 to create composite functions for Y3
	and Y4
	Y1 =	+ 1), Y2 = X2 + 3
	Assign Y1°Y2 to Y3, and Y2°Y1 to Y4.
	(Y1°Y2 =	((x2 + 3) +1) = 2 + 4) Y2°Y1 = ( (X + 1))2 + 3 = X + 4 (X > −1))

Input relations into Y3 and Y4.
