Need help with practice problem!

3. Suppose that K is the cuwe pictured to right that goes from y point A to point B to point C and ends at point D (Notice K is NOT a closed curve). Evaluate J(sin(x) + y)dx+ (3x +y)a_'y. K Hint: To do this in the most elegant way, use Green '3 Theorem, and calculate I (sin (x) + y) dx + (3x + y) dy where H H A a: (0, 0) is the line segment from D to A. D (o, 6) 01- (2. 4) B = (2. 2)
