1. You are given the point P in the cartesian coordinates (−4,
−4). Write the point in polar coordinates given the
restrictions:
(a) r > 0, and 0 ≤ θ < 2π. (in these programs, r = 0 is
just defined to be the origin).
(b) r<0andθ∈[0,2π)
(c) Write the point in polar coordinates that represent the
same point P but that
is different than the previous parts.

Given any Cartesian coordinates, (x,y), there are polar
coordinates (?,?)(r,θ) with −?2<?≤?2.−π2<θ≤π2.
Find polar coordinates with −?2<?≤?2−π2<θ≤π2 for the
following Cartesian coordinates:
(a) If (?,?)=(18,−10)(x,y)=(18,−10) then
(?,?)=((r,θ)=( , )),
(b) If (?,?)=(7,8)(x,y)=(7,8) then
(?,?)=((r,θ)=( , )),
(c) If (?,?)=(−10,6)(x,y)=(−10,6) then
(?,?)=((r,θ)=( , )),
(d) If (?,?)=(17,3)(x,y)=(17,3) then
(?,?)=((r,θ)=( , )),
(e) If (?,?)=(−7,−5)(x,y)=(−7,−5) then
(?,?)=((r,θ)=( , )),
(f) If (?,?)=(0,−1)(x,y)=(0,−1) then (?,?)=((r,θ)=( ,))

given the polar curve r = 2(1+cos theta) find the Cartesian
coordinates (x,y) of the point of the curve when theta = pi/2 and
find the slope of the tangent line to this polar curve at theta =
pi/2

Position and velocity of a point are given in polar coordinates
by R = 2, θ = 35 degrees, and
v = 4R + 3Θ. The 35
degrees is measured positive counterclockwise from the
x-axis on an xy Cartesian coordinate frame. What
is the velocity of the point in terms of i and
j?

The rectangular coordinates of a point are given. Plot the
point.
