Find the equation of the line tangent to the polar curve r = − 1 + cos θ at
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?
Write an equation for:
Evaluate your slope equation from Step 3 using the (rectangular) point (0, –1).
