I think the Greeks would have had a hard time with Taylor series, because they insisted that all numbers have units. You can't have X cm + (X cm)^2. Can one do unitless calculations geometrically?
X must refer to something such as a ratio of two lengths, not a number of centimeters. One can certainly view radians as unitless, being the ratio between an arc length and a radius. --Joshua
