Demetrios Iatropoulos

Demetrios Iatropoulos (Greek: ∆ημήτριος Ἰατρόπουλος; fl. 1260–95) was a senior Byzantine official of the late 13th century. He served as logothetes ton oikeiakon from 1260 until 1295, when he was promoted to protasekretis. He took part in the 1273 synod in Constantinople against patriarch John XI Bekkos, and is mentioned in 1281/2 as leading an embassy to the Empire of Trebizond.

gollark: Practice doing things under time pressure?

gollark: Differentiate it, substitute x=3 into that, set dy/dx to 0, solve.

gollark: Oh, actually just > 0 since it's a denominator, yes.

gollark: The $9-x^2$ bit has to have a value >= 0. So solve that and work out for which values it is >= 0.

gollark: You want the bit in the square root to be greater than or equal to 0, so just figure out what values of x give you that.
