Staff Review
This lesson is a good explanation of inverse trig functions, what they mean, and how they are graphed. A topic that is often quite difficult to understand and put on paper is done in a very straight-forward way. -

I like it but it would be appropriate to talk about why we restrict the range on the inverse sine. Reminder of one-to-one functions would help to fill in any gaps the viewer may have.
