Values of modular functions at real quadratics and conjectures of Kaneko

In 2008, Kaneko made several interesting observations about the values of the modular j invariant at real quadratic irrationalities. The values of modular functions at real quadratics are defined in terms of their cycle integrals along the associated geodesics. In this paper we prove some of the conjectures of Kaneko for a general modular function.
