Although this is a concise and clear explanation, I think you do it a disservice by starting out using degrees as an input value. Degrees is an arbitrary construct, while radians is the natural and inescapable defining element of the concept. I realize you have a separate video devoted to radians, but that could have been avoided by approaching it from the start, and include degrees as a side note. Degrees have their uses outside of pure engineering, but contribute nothing to the understanding of trigonometry. They are only a convenience.
