user-coordinates is the point (x

). The coordinates of the two other
corners both in pixel as well as in user-defined coordinates are shown in the
figure.
Animating graphics
Herein we present a way to produce animation by using the Y-Slice plot type.
Suppose that you want to animate the traveling wave, f(X,Y) = 2.5 sin(X-Y).
We can treat the X as time in the animation producing plots of f(X,Y) vs. Y for
different values of X. To produce this graph use the following:
• „ô simultaneously. Select Y-Slice for TYPE. ‘2.5*SIN(X-Y)’ for
EQ. ‘X’ for INDEP. Press L@@@OK@@@.
• „ò, simultaneously (in RPN mode). Use the following values:
• Press @ERASE @DRAW. Allow some time for the calculator to generate all
the needed graphics. When ready, it will show a traveling sinusoidal
wave in your screen.
