Inverse Functions Part 2: One to One Functions and the Horizontal Line Test

(Edited)

In this video I clarify the inverse functions in which I defined in my earlier video to state that it is only applicable to one to one functions. This requirement is illustrated in trigonometric functions which are not one to one and there inverse would require that an x value have multiple y values. I allude to how we avoid this restriction by restricting the domains of trig functions.
