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.)

第一问 每一行从左到右
0 30.00
π/12 72.19
π/6 111.50
π/4 145.26
π/3 171.26
5π/12 187.45
π/2 193.00
第二问是求一段弧长
the hand 转过了π/2 rad,弧长为163π/2≈256.04cm.
（图中的h应该是L）
(x -16)(x -4)=0 (x+4)(x-4)(x+2)(x-2)=0 所以x=-4,x=4,x=-2,x=2 y=f(x)=2x/(x+3) xy+3y=2x 2x-xy=3y x=3y/(2-y
3256 1115
额， 好吧
Seen from the figure, height h is a constant, does the “h” marked in the figure is actually "L" while ‘h' lists in the table refers to the height that the hand reaches?
