how would you sketch y= sin^-1 x + cos^-1 x. i know that there is a property where that would equal pie/2, but how do you use it?

It's a straight line, equivalent to y=pi/2

Oh, really, I think your contrition there was sufficient for missing the bleeding obvious. No need to drop 3unit.

Missing the obvious was one of my major problems, but I still did okay
