Question

Please help with my converting polar equations to rectangular?? **medal and fan**

1. r = 1
2. r = 4 / 2 - 2sin θ
3. r = 3 / 2 - 6sin θ
4. r = 2 / 2 - cos θ

Answer 1

Somebody please help? I don't know how to do this :(

Answer 2

\[r = \sqrt{x^2+y^2}\]
\[x=r \cos \theta\]
\[y = r \sin \theta\]

Answer 3

\[1. \sqrt{x^2+y^2}=1\]

2-4. Multiply by the denominator, distribute, then make the substitution
