Let C be the shorter of the two arcs of the unit circle centered at the origin that join the point (1,0) to the point (0,1). (In other words, C is a quarter of a circle in the positive quadrant.) (a) Setup, BUT DO NOT EVALUATE, an integral with respect to a parameter t that computes the value of the line integral y ds C . Hint: Use the parametrization x = cos t, y = sin t and write ds in terms of the parameter t.
