11-95.

To write the equation of the line, the slope, or dy/dx is needed.

For the given value of θ, where is the point on the curve?
What are the coordinates of this point in rectangular form?

$x=r\cos(\theta)=(-1+\cos(\theta))(\cos(\theta))$

$y=r\sin(\theta)=(-1+\cos(\theta))(\sin(\theta))$

Write an equation for:

Evaluate your slope equation from Step 3 using the (rectangular) point (0, –1).
