Question

Graph the polar equation. r = 2 + 2sin θ

Answer 1

The graph attached below is for r=2+ 2sin θ where θ=pi

Explanation

The coordinates in a polar equation are written as (r,θ)

r= radius and θ is the angle

⇒⇒⇒ so this mean we rotate θ radians and of the size r units

In our case assume θ=
`\pi` where 0≤θ≤2
`\pi`
