The following diagram is of the same plot as in the previous illustration,
but the axes now meet where x =1 and y =1.
Plotting programs
You can plot a program if it takes nothing from the stack, uses the
independent variable in the program, and returns exactly one mrtagged
number to the stack.
Examples
® Real result. Equivalent to the expressions/(,x) (function plots) and
'r(6) (polar plots). For example, the program:
« IF 'X<0' THEN ' 3*X''3-45X"'2 + 350 ' ELSE 1000 END »
plots/(x) = 3,x^-45x^+350 if x<0 and/(x) = 1000 if ,x>0.
Store the program in EQ, select autoscaling, and draw the plot.
® Complex result. Equivalent to (x(i), i/(0) (parametric plots). For
example, the program:
« 't^2-2' ^NUM 't"3-2t + l' ->NUM R^C »
plots the parametric equations x = t^-2 and x =
Store the program in EQ, make f the independent variable, select
autoscaling, and draw the plot.
