How do you graph #r=10costheta#?
1 Answer
The graph is the circle of radius 5 with center at (5, 0) on the initial line
Explanation:
The polar equation of the family of circles through the pole r = 0)
and center at (a. 0) is
So, here,
with parameter a = 5.
The general polar equation of the grand family of all circles, with
center at Cartesian
( from
As
the pole r = 0 is outside the circle.
Easy-to-remember direct polar form is
with the center at polar
In this example
Cartesian
Radius a = 5, and in the polar coordinates ,
the center is
