  The non-elementary integrals $\mbox{Si}_{\beta,\alpha}=\int [\sin{(\lambda
x^\beta)}/(\lambda x^\alpha)] dx,\beta\ge1,\alpha>\beta+1$ and
$\mbox{Ci}_{\beta,\alpha}=\int [\cos{(\lambda x^\beta)}/(\lambda x^\alpha)] dx,
\beta\ge1, \alpha>2\beta+1$, where $\{\beta,\alpha\}\in\mathbb{R}$, are
evaluated in terms of the hypergeometric function $_{2}F_3$. On the other hand,
the exponential integral $\mbox{Ei}_{\beta,\alpha}=\int (e^{\lambda
x^\beta}/x^\alpha) dx, \beta\ge1, \alpha>\beta+1$ is expressed in terms of
$_{2}F_2$. The method used to evaluate these integrals consists of expanding
the integrand as a Taylor series and integrating the series term by term.
