Question

convert to polar form
(x^2+y^2)^2 = 11(x^2 - y^2)

Answer 1

put x = r cos(theta) and y = r sin(theta)

Answer 2

then what?

Answer 3

That's the conversion into polar form

Answer 4

( r cos(theta)^2+ r sin(theta)^2)^2 = 11( r cos(theta)^2 - r sin(theta)^2)

Answer 5

simplify ... !!! that will be your answer.
