Polar Coordinates and Rectangular Coordinates

How do you write an ordered pair in polar coordinates?

• (X, Y)

• (θ, r)

• (r,θ)

• (Y_Y)

Find r
x=12
y=5

• 12

• 12.5

• 13

• 15

Convert from rectangular to polar coordinates. (-4, 4)

• (4√2, π/4)

• (4√2, 3π/4)

• (4√2, -π/4)

• (-4√2, -7π/4)

Match the point in polar coordinates with either A, B, C, or D on the graph.
(2, -11π/6)

• A

• B

• C

• D

Find the rectangular coordinates of the point:
(-2,0)

• (-2,0)

• (2,0)

• (π/2, 2)

• (√2, -2)

Match the point in polar coordinates with either A, B, C, or D on the graph.
(-2, π/6)

• A

• B

• C

• D

Match the point in polar coordinates with either A, B, C, or D on the graph.
(2, 5π/6)

• A

• B

• C

• D

In the coordinate points (2,7⁰) the 2 represents the...

• theta

• radius

• x

• angle

Convert from polar coordinates, (20, 11π/6) to rectangular coordinates.

• (-10√3, 10)

• (10√3, -10)

• (10, -10√3)

• (10√2, -10)

When converting between rectangular and polar coordinates:

y = ?

• rcosθ

• rsinθ

• x² + y²

• y/x, x ≠ 0
