- We compute the integral of monomials of the form $x^{2β}$ over the unit sphere and the unit ball in $R^n$ where $β= (β_1,...,β_n)$ is a multi-index with real components $β_k > -1/2$, $1 \le k \le n$, and discuss their asymptotic behavior as some, or all, $β_k \to\infty$. This allows for the evaluation of integrals involving circular and hyperbolic trigonometric functions over the unit sphere and the unit ball in $ R^n$. We also consider the Fourier transform of monomials $x^α$ restricted to the unit sphere in $R^n$, where the multi-indices $α$ have integer components, and discuss their behaviour at the origin.
