Find the point(s) of intersection for the polar curves with equations r = 1 − cos θ and equations r = 1 + cos θ.

Question

Find the point(s) of intersection for the polar curves with equations r = 1 − cos θ and equations r = 1 + cos θ. (4 points)

answer choices

	0, π

Answer 1

r = 1 + cos θ. r = 1 - cos θ

1 + cos θ = 1 - cos θ

2 cos θ = 0

cos θ = π / 2 , 3 π / 2
