Rod,
The terms “cosine loss” and “cosine gain” already existed before AWE usage. I did not invent them, nor was I first to use “cosine loss” in AWE.
This topic is about cosine functions generally in various kite geometry instances. How can I reasonably abandon hope you can understand or at least tolerate “cosine gain”, along with “cosine loss”, as acceptable terms in AWE geometric discussion?
We adopt, adapt, or coin new terms all the time in AWE, including “AWE” itself.
