What is the polar form of the equation (x+2)2+y2=4?

  • r(r+4cosθ)=0
  • r(r+4sinθ)=0
  • r2=4rsinθ
  • r2=4rcosθ

 

Question 2

 

What is the rectangular form of the polar equation \(θ={−5π\over6}\)?

\(y= \sqrt{3}x\)

\(y= {\sqrt{-3}\over 3} x\)

\(y={ \sqrt{3}\over 3}x\)

\(y= \sqrt{-3}x\)

 

For 2, can you show me how?
