Express each function as a trigonometric function of x. See Example 5.cos 3x. Cos3x is an important identity in trigonometry, which is used to determine the value of the cosine function for an angle that is thrice the measure of angle x. ... cos(3x). Figure 5 shows the zero level set of visibility function for an observer at (0.02, 0.02, f (0.02, 0.02)) where f = cos(5 x 2 + y 2 π) − 4(x 2 + y ...
