Question

I need help with finding coordinates! Thanks for helping!


I need to find two polar coordinates for each graph. Thank you for helping!

Answer 3

how far from the pole (aka the origin) is that red point?

Answer 4

2.5

Answer 5

@jim_thompson5910

Answer 6

so that is the r value

Answer 7

theta = 5pi/3 is the angle

Answer 8

(r,theta) = (2.5, 5pi/3)

Answer 9

so if I needed another angle, would I add 2pi?

Answer 10

or subtract 2pi

Answer 11

or you can say

(r,theta) = (-2.5, 2pi/3)

Answer 12

11pi/3

Answer 13

start facing the 2pi/3 direction

then walk backwards 2.5 units

Answer 14

oh

Answer 15

saying 11pi/3 is acceptable as well right?

Answer 16

yeah

(2.5, 5pi/3)
(2.5, 11pi/3)
(-2.5, 2pi/3)

are all the same point

Answer 17

For the second one could I put (3, 3pi/2) and (3, 7 pi/2)

Answer 18

r = 4 it looks like it

but for some reason they didn't label the scale

Answer 19

my bad, I meant 4. Thanks for the help!

Answer 20

(4, 3pi/2)
(4, 7pi/2)
(-4,pi/2)
are 3 of infinitely many ways to label that point

Answer 21

Thanks :D
