(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

r=2-3cosθ Find the tangent line at any point, and at the point (2,∏) Find the tangent line(s) at the pole

2. Relevant equations

Do I have to use x=rcosθ and y=rsinθ to convert it to rectangular to find slopes?

3. The attempt at a solution

Is the point 2∏ even a point in the graph. It is a limicon (sp?) graph?
