Question

Convert the rectangular equation to polar form x^2+y^2=9

Answer 1

r=3

Explanation:

Answer 2

polar form is (r,θ) where r is the radius and tan θ = x/y

The equation you provided is a circle so 9 = r² → r = 3

tan θ = 1/1
tan θ = 1

`tan^(-1)` (tan θ) =
`tan^(-1)` (1)
θ = 45°

Answer: (3, 45°) or (3,
`( \pi)/(4)`)
