Apologies for the confusion, it's an O for Offset. This should make it a little clearer, (HSO being Horizontal Sightline Offset). HSO=R{1-Cos(28.65S/R)} But what your saying, you can't solve the above equation for R. Might explain why I couldn't, apart from my poor maths. Thanks for your help.

Hey all, I need some help rearranging for R. O=R{1-Cos(28.65S/R)} For those curious, its a Horizontal Sightline Offset formula used in geometric road design. thanks
