Y

Overview
Y (minuscule: y) is the twenty-fifth and penultimate letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages, and others worldwide. According to some authorities, it is the sixth (or seventh if including W) vowel letter of the English alphabet. Its name in English is wye (pronounced ), plural wyes.
In the English writing system, it mostly represents a vowel and seldom a consonant, and in other orthographies it may represent a vowel or a consonant.

X = β_x_, Y = γ_y_, Z = δ_z_. [β ≠ γ ≠ δ.] They proceed to adjust their differences, and first take the _x_-coordinates. Obviously they have taken different units of length along O_x_. The length OU_{1}, which A calls one unit, B calls β units.

I now calculate further with these formulae. I treat dx and dy as real quantities, as quantities subject to certain exceptional laws, and at a certain point I negate the negation, that is, I integrate the differential formula. I get instead of dx and dy the real quantities x and y again, and am thereby no further forward than at the beginning, but I have thereby solved the problem over which ordinary geometry and…
