Dean Eddie Perry is hiking up the side of a mountain, along a trail that has a lot of switchbacks. His position is given by †(t) = (2 – , (0.5 – ) cos(4rt), 0.3+0.2t) where x, y, z are measured in miles and t is in hours. Eddie begins his hike at time t = 0 and reaches the summit at t = 4 hours. a. Find Eddie's position after two hours. b. Find Eddie's velocity vector after two hours. c. Set up an integral to calculate the length of the entire trail. Then use technology to evaluate your integral.
