Polar Coordinates

Is a plane with a point O, the pole and a ray from 0, the polar axis.

A quick “how to”…

Examples A (2, 45º)

B (-1.5, )

C ( 3, -30º)

D (-1, )2

Converting Polar and Rectangular Coordinates

Converting from Polar to Rectangular

1. P(3, )

2. Q(2, -200º)

65

Converting from Rectangular to Polar

1. P(-1, 1)

2. Q(-3, 0)

Equation Conversion:(from polar to rectangular)

r = 4 sec Ө

Equation Conversion:(from rectangular to polar)

(x-3)2 + (y-2)2 = 13
