yEx-r 1. Turn in: Problem 37 of Section 4.4, 12th edition. 2. Turn in: Problem 40 of Section 4.4, 12th edition. y = x + sin x NW 3. Turn in: Use Desmos to graph the function y = x vx3 + 1 then find the area under this curve over the interval xe [-1 , 2] 4. Turn in: The graph for y = e*/2 -1 is as shown. Find the area for the shaded region over the interval xe [-2 , 4] 5. Turn in: The velocity of an object is defined as: I = (sin 2t -cost ) ft/s . Initially, the object is located at s(0) =1 ft . Determine the position of this object at 1 =- - sec 2
