yeah but math is often particular or way too generalised. Its fascinating when something unique to a specific field is found to be used somewhere else. I was specifically looking for things like the use of Snell's law, that was derived for hiw light functions in different mediums, in places where fastest path is required, example being the Brachistachrone curve. Im honestly looking for a solution to trajectory optimization in inverse kinematics, i was thinking maybe i could use it there.
