In the past, I supervised exercise classes in the following subjects at the University of Innsbruck and the University of Freiburg:

•  Linear Algebra 1-2
• Analysis 1
• Algebra und Number Theory
• Commutative Algebra
• Elementary Geometry

For me, the connection between Latin studies and Mathematics is primarily of historic interest, which is rooted in the following reasons.

• For the most part of modern time (~ 1450-1750), Latin was the language of science. Many groundbreaking results were first published in Latin. Jakob Bernoulli published his ideas on probability theory in 1713 in the treatise Ars Coniectandi. Other famous examples for the significance of the Latin language are Gauß' Disquisitiones Arithmeticae (1801) or the diverse works of Leonhard Euler. In 1889 still, Giuseppe Peano published his Arithmetices Principia in Latin. These works and ideas cannot be read in their original form without knowledge of the Latin language.
• More general one should ask about the history of Mathematics. From this perspective, many recent and elaborate results can be motivated. As an example, axiomatic geometry can be developed purely from incidence realtions and related concepts. But its origins lie in Euclid's Elements - along with the extensive discussion (often in Latin) of the famous parallel postulate in the subsequent centuries. Based on this approach, today's axioms are just a natural abstraction of the intuition in ancient times. This natural process is traced very well in the book Geometry: Euclid and Beyond (Robin Hartshorne, 2000).
• Neo-Latin mathemtaical treatises are interesting in and of themselves, precisely because they do not conform to today's norms on mathematical literature. They often convey a completely different intent, but do so in the language of Mathematics. As an example, in a New Year's letter to a friend, Johannes Kepler writes about sexangular snowflakes (De nive sexangula, 1611), but also states Kepler's Conjecture, which has been proven only recently.

Nihil equidem magis opto, quam ut iis, quibus scientiarum incrementa cori sunt, placeant, quae vel hactenus desiderate explent, val aditum ad nove aperiunt. (C.F. Gauß, Disquisitiones Arithmeticae, p. XII)
And I desire nothing more than that all those, to whom the promotion of scientific knowledge is important, will find joy in these ideas, which either solve problems that had been unsolved so far, or which show the way to new insight.
