Answer
$x=u, \quad \sin u \cos v =y\quad \sin u \sin v=z$ is a parametrization for the surface resulting from $\sin x=y$ about the $x$ axis.
Work Step by Step
Our function is $\sin x=y$
Since we revolved this function about the $x$ axis, $x$ is a free parameter, ie. we can take $u=x,$ and then
\[
\sin u \cos v =y \text { and } \sin u \sin v=z
\]
$x=u, \quad \sin u \cos v =y\quad \sin u \sin v=z$ is a parametrization for the surface resulting from $\sin x=y$ about the $x$ axis.
