Final answer:
The polar form of x - y = 0 is θ = π/4 or θ = 5π/4.
Step-by-step explanation:
The equation x - y = 0 represents a linear equation in Cartesian coordinates. To convert it into polar form, we need to express x and y in terms of polar variables r and θ.
Given that x = rcosθ and y = rsinθ, we can substitute these expressions into the given equation:
rcosθ - rsinθ = 0
Factoring out r:
r(cosθ - sinθ) = 0
Therefore, the equation in polar form is θ = π/4 or θ = 5π/4.
