Question: -W In a laser projection system, the optical or scanning angle 0 is related to the throw distance D from the scanner to the screen

-W In a laser projection system, the optical or scanning angle

-W In a laser projection system, the optical or scanning angle 0 is related to the throw distance D from the scanner to the screen and the projected image width W by the equation D = csCO - cote . Use the given information to answer parts (a) and (b). (a) Show that the projected image width is given by W = 2D tan D = Given. csco- cote 1 : -W = W = W Use definition of trigonometric functions. = W Simplify. 2D tan = = W (b) Find the optical angle if the throw distance is 19 feet and the projected image width is 6.3 feet. 0=(Round to the nearest hundredth as needed.)
