Radians - A query

Crucifix · 2005-01-15 13:08:16

Ok, I've been using radians since honours maths for the LC, and now that they've come up again in college physics I just want to know, is it the length of the curve on the arc over the radius, or the length between the start and finish of the curve on the arc over the radius?

If I'm reading you right, it's the length of the arc. Think about the full circle, it's the length of the circle over the radius, which is 2*pi ...
