Convert r = 8cos θ to rectangular form.
skelet666 [1.2K]

Answer:

D

Step-by-step explanation:

To convert from polar to rectangular form

• x = rcosΘ , y = rsinΘ

• r = \sqrt{x^2+y^2} ⇒ r² = x² + y²

Given

r = 8cosΘ

r = 8 × \frac{x}{r} ( multiply both sides by r )

r² = 8x, hence

x² + y² = 8x ⇒ D
