We will try to plot the function f(θ) = 2(1-sin(θ)), as follows:

Θ First, make sure that your calculator’s angle measure is set to radians.

Θ Press „ô, simultaneously if in RPN mode, to access to the PLOT

SETUP window.

Θ Change

TYPE to Polar, by pressing @CHOOS ˜ @@@OK@@@.

Θ Press ˜ and type:

³2* „ Ü1-S~‚t @@@OK@@@.

Θ The cursor is now in the

Indep field. Press ³~‚t @@@OK@@@ to

change the independent variable to θ.

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

Θ Press „ò, simultaneously if in RPN mode, to access the PLOT

window (in this case it will be called PLOT –POLAR window).

Θ Change the H-VIEW range to –8 to 8, by using

8\@@@OK@@@8@@@OK@@@, and the V-VIEW range to -6 to 2 by using

6\@@@OK@@@2@@@OK@@@.

Θ Change the

Indep Low value to 0, and the High value to 6.28 (≈ 2π), by

using: 0@@@OK@@@ 6.28@@@OK@@@.

Θ Press @ERASE @DRAW to plot the function in polar coordinates. The result is a

curve shaped like a hearth. This curve is known as a cardiod (

cardios,

Greek for heart).

Θ Press @EDIT L @LABEL @MENU to see the graph with labels. Press L to

recover the menu. Press L @)PICT to recover the original graphics menu.

Θ Press @TRACE @x,y@ to trace the curve. The data shown at the bottom of the

display is the angle θ and the radius r, although the latter is labeled Y

(default name of dependent variable).

Note: the H-VIEW and V-VIEW determine the scales of the display

window only, and their ranges are not related to the range of values of

the independent variable in this case.
