Yah, that last one wasn't so good. It has been pointed out to me that all of your webwork on Green's theorem dealt with using a double integral to find the value of a line integral, whereas the quiz did the reverse: it asked you to find an area by computing a line integral.
OK.
So I'm going to give another quiz on exactly the same topic as the last: finding the area of a region by computing a line integral around the boundary. I'll give you a parameterization of the boundary, just like before. ALL YOU NEED TO KNOW HOW TO DO IS TO COMPUTE THE AREA BY USING A LINE INTEGRAL.
