INVERSE TRIG FUNCTIONS Basic Graphs (Page 12 of 13)

Before concluding this topic, there is one more issue worth exploring. We have graphed all six of the inverse trigonometric functions in radian mode. It is possible to obtain each of these graphs in degree mode as well. The only difference would be in setting the window.

For example, let's show the previous graph, the inverse secant function, in degree mode. First, change to Degree mode, then change the WINDOW settings so that Ymin = -10,  Ymax = 190 and Yscl = 90.

 MODE key. [Degree] ENTER key.

 WINDOW key....
