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

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?
