Trigonometric function Image

Obviously, when x is an odd multiple of = 2, y = tan (x) has a vertical gradient (undefined ). in addition, the symmetry of the image indicates that tan (x) is an odd function of x.

Function images of y = sec (x), y = csc (x), and y = cot (x) are also worth learning, 2-20, Fig 2-21, and fig 2-22.
