# What is the graph of #y=cos^-1x#?

Since *Technically* if

However, since this is supposed to be a function, and the

Here's the final graph:

graph{y = arccos x [-4, 4, -1, 4]}

Kind of weird, isn't it? A non-continuous graph!

Because this is the "positive" portion of the cosine curve rotated 90 degrees, it will have a domain (x-value range) of -1 to 1, and a range (y-value range) of 0 to
