Graph of a function in Polar coordinates
To plot the function in polar coordinates r = r( j )
select Polar in the Choose Curve Type window, press OK and enter curve definition
in one of the following formats:
R(fi)         to define graph for full range of argument
R(fi);A,B        to define graph for
j in the segment [A,B] only,
where R(fi) is an expression, depending only on variable fi
A,B - numbers,
Tip. Expression can contain other variables, if they have numeric values.
To
change name of variable, associated with polar angle, select Command-> Graph Property
and change names on the Names tab.
Examples:

3*sin(fi)                              means r=3*sin (j)
3*sin(fi);0,pi                            means
r=3*sin (j)    in [0, p]
