Please answer all of the following questions (questions 1-7). Show all your work.

1.) Find the Cartesian coordinates of the given polar coordinates. Then plot the point.

(a) (4, π)

(b) (4, −2π/3)

(c) (−4, 3π/4)

2.) The Cartesian coordinates of a point are given.

(a) (4, −4)

(i) Find polar coordinates (r, θ) of the point, where r > 0 and 0 ≤ θ < 2π.

3.) Find two other pairs of polar coordinates of the given polar coordinate, one with r > 0

and one with r < 0.

Then plot the point.

(a) (2, 7π/4)

(r, θ) = (r > 0)(r, θ) = (r < 0)

(b) (−5, π/3)
