    Answers must be explained very clearly. Answers without proper justification will not be accepted. I am having a lot of trouble with these questions and the last time I posted this the TA just gave me a bunch of BS. Please take your time and answer these questions clearly and accurately with step by step work so I can follow along. Thanks and have fun.

    Question 1

    Given the polar function r = 2 - 2cos

    a) Find the parametric equations for the function (i.e., x=....'s, y=...'s.)

    b) Find the derivative, dy/dx

    c) Find all vertical tangent lines and singular points

    Question 2

    Given the two polar equations r1 = 2 - 2cos and r2 = 3

    a) Find the values of  where r1 intersects r2 (Please show graph)
    b) Find the arc length or r1 on the interval 's found in part a.
    c) Set up the integral to find the area of the surface of revolution for the segment of r1 on the same interval of 's found in part a when rotated about the pole (x-axis).
    d) Set up the integrals to find the area of the region bounded on the left by r1 and on the right by r2

    Resources:
    I am using the book Calculus, Larson, Hostetler, and Edwards, Seventh edition.
