f F X 1. Calculate the line integral F ds for the function = zi+x- yk over a square path of side s whose left corner is at the origin (0, 0, 0), and lies in the xy-plane. 2. What is the value of the loop integral fVf ds, where f is a scalar function? 3. Determine the value of the line integral f F.ds, where along the path Y F = (e = ze) + (e* xe) j + (e* ye) k, - 80 = y = = Z = In 2 In (1 + p) sin (TP) (+2) 1-eP 1-e' - where 0 p 1, from (0, 0, 0) to (1, 1, 1). Hint: think before you write!
