Did the calculation and posted results here. I only need 1.99 or 2.098" rise to get 4* depending on the legnth of the run. Pretty nifty simple calculation. This would have been the way to learn math back in school. If only my trig teacher had known or cared... if only I'd had the sense or luck to see the purposes I might love.

There are also apps for your phone that can "solve" triangles. Obviously you need to enter a few variables, but they will usually give you the types of answers you are looking for without having to know or remember any bit of trig. I myself am using Triangle Solve for the iPhone.

I use android and just got and tested the free "triangle calculator" from "Google Play." I got the same results from it for the angle and rise that I got from doing the numbers myself, though only to the hundredth place (good enough) Still, I needed to measure on a flat surface or I would not know that i have just over 4" to work with, filling only 2.1" with the rise at the trailing edge of the diffuser. I need 2" more of "filler" at the back of the diffuser.
