QUESTION
What circle does
r
=
2
cos
(
θ
)
r=2\cos(\theta)
r
=
2
cos
(
θ
)
represent (center and radius)?
QUESTION
Convert the Cartesian point
(
x
,
y
)
=
(
−
3
,
1
)
(x,y)=(-\sqrt{3},1)
(
x
,
y
)
=
(
−
3
,
1
)
to polar with
r

ANSWER
(
x
,
y
)
=
(
1
,
3
)
(x,y)=(1,\sqrt{3})
(
x
,
y
)
=
(
1
,
3
)
.
x
=
2
cos
(
π
3
)
=
1
x=2\cos(\frac{\pi}{3})=1
x
=
2
cos
(
3
π
)
=
1
,
y
=
2
sin
(
π
3
)
=
3
y=2\sin(\frac{\pi}{3})=\sqrt{3}
y
=
2
sin
(
3
π
)
=
3
