Problem 2. Evaluate the line integral
int_C (2x+y)dx+(3x-y)dy
where C consists of the four line segments from (-1,0) to (1,0), then from (1,0) to (1,1), then from (1,1) to (-1,1), and finally from (-1,1) to (-1,0). The closed curve C is a rectangle with the four corners at (-1,0),(1,0),(1,1),(-1,1).
