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]
