The Force F(in pounds) on a person's back when he or she bends over at an angle 6 from an upright position is modeled by = 0.6W sin(6 + 90] sin(12) F where W represents the person's weight (in pounds). (a) Simplify the model. F= (b) Use a graphing util'ty to graph the model, where W = 195 and 0 S 6 S 90. At what angle (in degrees) is the force maximized? At what angle (in degrees) is the force minimized? (a) Write a sum formula for sin(u + v + w). sin(u+v+w) = (b) Write a sum formula for tar1(u + v + w). tan(u+ v+ w) = Find the solution of each inequality in the interval [0, 213:). (Enter your answers using interval notation.) (a) sin(x) 2 0.5 (b) cos(x) s D.5 (c) 2 tan(x)
