Abstract: We show that integrating a (positively) homogeneous function $f$ on a compact domain $\Omega\subset R^n$ reduces to integrating a related function on the boundary $\partial{\Omega}$. The formula simplifies when the boundary $\partial{\Omega}$ is determined by homogeneous functions. Similar results are also presented for integration of exponentials and logarithms of homogeneous functions.
