Question
1.
Match each equation in rectangular coordinates with its equation in polar coordinates:
(a) x² + y² = 4
O
r²(1-2 sin² 0) = 4
r(cos 0 + sin() = 4
r = 2 sin 0
Or=2
(b) x² + (y − 1)² = 1
O r²(1-2 sin²0) = 4
r(cos+ sin 0) = 4
r=2 sin 0
r = 2
(c) x+y=4
Or² (1-2 sin² 0) = 4
r(cos+ sin 0) = 4
r = 2 sin 0
Or=2
