inverse functions

We have seen how the graph of the sine
function is not one to one, and hence the
inverse will not be a function.
So, we limit the domain of the sine function on
the inverval < x<. Then it is one to one
and still encompasses the entire range -1 s
y< 1. When we reflect across y = x, we get
the inverse sine function.
On your own piece of paper, draw a coordinate system like the one below. Your task is
to limit the domain on the tangent function on the same interval and then reflect it
across the line y=x to obtain the inverse tangent function.
Unfortunately, the interval –<x< won't work for the cosine function.
We use the interval 0 < x < n. On your own piece of paper, draw a coordinate system
like the one below. Then draw a graph of y = cos x on this interval and then reflect
over the line y =x to obtain the graph of the inverse cosine function.
