Hey, Simple questions, and hopefully I can explain my query a bit better than others I have made. I'm just trying to think of any advantages for using radians instead of degrees? I know/think that degrees are an arbitrary unit but cannot think of any reasons for using 360. 1. What are the advantages of using radians? 2. If degrees are an arbitrary unit then, where did the number 360 come from? Is it some how related to time, with 60 being a multiple of 360. 3. Am I correct in saying that to convert 1 degree to radians I would use, 1 x π/180, and if converting 1 radian to degrees, I would use 1 x 180/π Thanks.
