{ ‘(X-1)^2+(Y-2)^2=3’ , ‘X^2/4+Y^2/3=1’ }

into the variable EQ.

These equations we recognize as those of a circle centered at (1,2) with

radius √3, and of an ellipse centered at (0,0) with semi-axis lengths a = 2 and

b = √3.

• Enter the PLOT environment, by pressing „ô, simultaneously if in

RPN mode, and select Conic as the TYPE. The list of equations will be

listed in the EQ field.

• Make sure that the independent variable (Indep) is set to ‘X’ and the

dependent variable (Depnd) to ‘Y’.

• Press L@@@OK@@@ to return to normal calculator display.

• Enter the PLOT WINDOW environment, by pressing „ò,

simultaneously if in RPN mode.

• Change the range for H-VIEW to -3 to 3, by using

3\@@@OK@@@3@@@OK@@@. Also, change the V-VIEW range to -1.5 to 2 by

using 1.5\@@@OK@@@ 2@@@OK@@@.

• Change the Indep Low: and High: fields to Default by using L @RESET

while each of those fields is highlighted. Select the option Reset value

after pressing @RESET. Press @@@OK@@@ to complete the resetting of values.

Press L to return to the main menu.

• Plot the graph: @ERASE @DRAW.

Note: The

H-View and V-View ranges were selected to show the intersection

of the two curves. There is no general rule to select those ranges, except

based on what we know about the curves. For example, for the equations

shown above, we know that the circle will extend from -3+1 = -2 to 3+1 = 4

in x, and from -3+2=-1 to 3+2=5 in y. In addition, the ellipse, which is
