1. (3.5pts) Suppose that K is the curve pictured to right which goes from point A to point B to point C and ends at point D (Notice K is NOT a closed curve). Evaluate D = (0, 6) (sin (x) + y)dx +(3x+ y) dy . Hint: To do this in the most elegant way, use C- (2,4 ) K Green's Theorem, and calculate (sin(x) + y)dx+ (3x+ y)dy where is H is the B - (2, 2) H A = (0, 0) X line segment from D to A
