Question

write rectangular equation in polar form
y=2 write rectangular equation in polar form
y=2 @Mathematics

Answer 1

i think they want you to convert the graph y=2 in the Cartesian form to polar form correct?

Answer 2

yes that is what they want you to do

Answer 3

do you remember what x =s and what y =s?

Answer 4

you should memorize that x=rcostheta and y = r sintheta

Answer 5

you can substitue in rcostheta in for x and then solve for r

Answer 6

exactly polar is in (r,theta)

Answer 7

yep so since x = r cos theta.. just put that in for x then solve for r

Answer 8

what do you get?

Answer 9

oh im sorry youd use the y one

Answer 10

y = r sin theta

Answer 11

r sin theta = 2

r = 2/sin(theta)
