Question

Convert the polar equation to rectangular coordinates: r=8sec(theta)

Answer 1

mutiply both side by
r^2 =r*8sec(theta)
but r^2=
hence
x^2+y^2=8rsec(theta)
hence x^2+y^2-8rsec(theta)=0

Answer 2

how would use that to find the rectangular coordinates?

Answer 3

i managed to find x which is 8 by substituting rcos(theta) into the original

Answer 4

but i'm struggling to find y

Answer 5

put your answer of x in my answer you will get answer for y..

Answer 6

but you have three variables: x, y, and theta. i only have x
