The cartesian coordinates of a point are given. (a) (−2, 2) (i) find polar coordinates (r, θ) of the point, where r > 0 and 0 ≤ θ < 2π. (r, θ) = incorrect: your answer is incorrect. (ii) find polar coordinates (r, θ) of the point, where r < 0 and 0 ≤ θ < 2π. (r, θ) = incorrect: your answer is incorrect. (b) (5, 5 3 ) (i) find polar coordinates (r, θ) of the point, where r > 0 and 0 ≤ θ < 2π. (r, θ) = incorrect: your answer is incorrect. (ii) find polar coordinates (r, θ) of the point, where r < 0 and 0 ≤ θ < 2π. (r, θ) = incorrect: your answer is incorrect.
