Web4. Evaluate the line integral R C sinx dx+cosy dy, where C consists of the top half of the circle x2 +y2 = 1 from (1;0) to ( 1;0) and the line segment from ( 1;0) to ( 2;3). If we split the curve into two parts we can nd a parameterization for each part and then continue as in 3. Let’s instead use the Fundamental Theorem of Line Integrals.
