Query: Exact formulas for traces of singular moduli of higher level modular
  functions   Zagier proved that the traces of singular values of the classical j-invariant
are the Fourier coefficients of a weight 3/2 modular form and Duke provided a
new proof of the result by establishing an exact formula for the traces using
Niebur's work on a certain class of non-holomorphic modular forms. In this
short note, by utilizing Niebur's work again, we generalize Duke's result to
exact formulas for traces of singular moduli of higher level modular functions.
