Question

Help with Polar coordinates

Answer 1

For the following polar coordinate (3, 345°), find a pair of alternative coordinates with a negative r value and a negative θ value.

I am confused, would we switch around the equation that we would use to find alternative coordinates?

Answer 2

(-r(-Theta+180)+360n?)

Answer 3

" pair of alternative coordinates"
so i think they need 2 co-ordinates,

one with a negative r value

and one with a negative theta

Answer 4

They didn't mention that you need to find cartestian co-ordinates...buts lets assume they're asking for it...

(-3, 345)
x =-3 cos 345
y = -3 sin 345

(3, -345)
x =3 cos -345
y =3 sin -345

Answer 5

if they're just asking another polar co-ordinates, then its just

(-3, 345) and (3,-345)

Answer 6

Wait wait so all you have to do is switch the points to negative ><

Answer 7

yes,
"with a negative r value and a negative θ value."

r was 3, so r =-3

Answer 8

So i know x=-3 and then i get -44.49

Answer 9

our starting quadrant was 3rd right?

Answer 10

lets plot it
