124 Chapter 5 Graphing and Inverse Functions §5.3 The inverse tangent function y = tan 1 x (sometimes called the arc tangent and de- noted by y = arctan x ) can be determined similarly. The function y = tan x is one-to-one over the interval ( π 2 , π 2 ) , as we see in Figure 5.3.8: x y 0 3 2 1 1 2 3 π 4 π 2 π 4 π 2 y = tan x Figure 5.3.8 y = tan x with x restricted to ( π 2 , π 2 ) The graph of y = tan 1 x is shown below in Figure 5.3.9.
