Question

How do you write r=2sintheta and r=2sin2theta into polar coordinates?

Answer 1

it is polar coordinates

Answer 2

r = 2 sin theta, theta is theta

Answer 3

maybe you mean cartesian coordinates?

Answer 4

it says solve the system of equations on the polar plane: then it has those two equations. And says Write your solutions as polar coordinates [hint there are 4]

Answer 5

oh

Answer 6

yeah ha. Do you know anyone who could help?

Answer 7

yes me, give me medal

Answer 8

I don't know how to?

Answer 9

i just gave you medal

Answer 10

but how

Answer 11

i took it away your medal

Answer 12

solve 2 sin t = 2 sin (2t)

Answer 13

Ah, it's already in polar coordinates. (r, theta)

Answer 14

assume that r1 = r2 , where r1 = 2 sin t , and r2 = 2 sin (2t)

Answer 15

2 sin t = 2 ( 2 sin t cos t )

Answer 16

woah slow down haha

Answer 17

2sin t - 4sint*cost = 0

Answer 18

more medals

Answer 19

2sin t ( 1 - 2 cos t ) = 0

Answer 20

how is that four solutions

Answer 21

solve

Answer 22

solve

Answer 23

solve what?

Answer 24

2sin t = 0 or 1- cos t = 0

Answer 25

helppppp

Answer 26

sin t = 0 when t = 0, pi ,

Answer 27

1- 2 cos t = 0 when cos t = 1/2 , when t = pi/3, 5pi/3

Answer 28

so the solutions are t = { 0, pi, pi/3, 5pi/3}

Answer 29

how do i show the work? what do I write for the equations and what answer goes with which one

Answer 30

Did you use the right equations? 2sint and 2sin2t

Answer 31

never mind i got it. thanks (:
