This is multivariable calculaus question, please I need the answer to be hand-written. Please no guessing if you don't know don't answer

(Part A is two points; Part B is two points; Part C is two points.) Part A. Determine if the given set is simply-connected: the region inside the polygonal line joining the points in the following order (5, 5), (114% (1,2): (3,3), (570)- Part B. Given F : ~C($(1 + y2)i + x2j), where C is a constant and the domain U = R2 of F is simplyconnected. Determine whether F is conservative. Part C. Do not evaluate the iterated integral. Express the iterated integral as an equivalent integral with the order of integration reversed. 1 7r / 4 f / :vzydmdy 0 arctan(y)
