How can I write the equation for this tangent circle?
Fundamental circle is $r=3\sin(\theta)$ and I also find the tangent line for $\theta = \frac{\pi}{3}$
And the tangent line to the circle is:
$y=-\sqrt{3}x+\frac{9}{2}$ And that is:
I wonder how can I write the circle equation in polar coordinates for the circle which center is C. Thanks!
