This has been a good discussion. It made me think of an old (5 years) TI calculator I had. It had as an mode option: degrees, radians or GRADIENTS. I could never figure out or locate any information on what a gradient was or is. Just as a curiosity does anyone know? The closest I could come to clearing it up was SIN(100 gradients)=1. Does that mean 100 gradients is pi/2 rads.??
Was gradient measure an attempt to "metricize" rotational measure? Does anyone use it now or ever???
