Similarly you can calculate the Sub-style Height, the angle of the gnomon to the wall, as Sin SH = Cos Dec x Cos Lat. But this is not how Zarbula did it. He only had available a stick, some string and the sun. I will leave that as a homework exercise.
Hi Roger,Are you going to leave us dangling, or are you willing to tell us how Zarbula found SH with a stick, some string and the Sun?
