Question

convert the rectanguler equation to a polar equation. Express r in terms of theta.

y-x=8

so is it just x^2-y^2=64 r=8? but thats not theta....

Answer 1

you ve done it wrong
y = r cos(theta)
x = r sin(theta)

Answer 2

y - x = 8
r cos(theta) - r sin(theta) = 8
r (cos(theta) - sin(theta)) = 8

r = 8/(cos(theta)-sin(theta))

Answer 3

thank you
