12. A Norman window (A rectangle with a semicircle on top.) has a perimeter of 37 feet. Find the dimensions of the window that will has the largest possible area. (12 points) When finding antiderivatives, the integrand must be in basic forms before integrating. If using u-sub, you must give your choice of u, du, and derive anything else necessary for the substitution. 13. Find F(x) if f(x) = 3 tan x + secx + 4x and F () = V3 (12 pts)
