I also wanted to include special angles (particularly tangent) and shaded in representations for the inverse trig functions. I couldn't find anything to meet that need, so I created one myself. I hope your students enjoy this as much as mine do! I also have a Trigonom

The trig values are in exact fraction form, no slashes. I give this to my PreCalculus and Calculus students the first week of class in a plastic page protector and tell them to keep it handy (except during tests). It certainly is an improvement over having them stare at the ceiling when they need sin(
