The force F (in pounds) on a person’s back when he or she bends
over at an angle e from an upright position is modeled by
F= 0.6W sin (θ+90)/ sin 12°
where W represents the person’s weight (in pounds).
(a) Simplify the model.
(b) Use a graphing utility to graph the model, where
W = 185 and 0° <e < 90°. (Link if you can plz)
(c) At what angle is the force maximized? At what angle is the force
