Evaluate $\displaystyle \int_Csinxdx+cosydy$ where C is the top half of the circle $\displaystyle x^2+y^2=4$ from (2,0) to (-2,0) and the line segment from (-2,0) to (-3,2).

Haven't done vector calc in awhile, still a little bit rusty, can someone assist me with getting the parametric equations for the line segment?
