I wasn't knocking your post 8thTon, but actually trying to put it together in a way I could understand. It looks like someone made some sense of it somehow and I was hoping to grasp at least a bit of it. I did some architectural engineering in my early years and to this day have a collection of books full of formulas, but I'm not in tune with a lot of the newer ones. Sines, cosines, and tangents were mostly what were used in building design, basic trigonometry, but I've also tinkered with many others since then, mostly just out of curiosity, a simple tendency to try and figure things out, which for some reason seems to lean towards mathematical terms(or at least in the physical realm)
