200分求数学题
Trigonometric functions are used extensively in the design of industrial robots.Suppose that a robot's shoulder joint is motorized so that the angle θ increases at a constant rate of 派/12 radian per second from an initial angle of θ = 0.Assume that the elbow joint is always kept straight and that the arm has a constant length d = 163 centimeters,as shown in the figure.
第一问问已经截图了
第二问是,Find the total distance that the hand moves.(Round your answer to two decimal places.)
