13. The equation of the ecliptic in equatorial coordinates $(\alpha,\delta)$ has the form:

$\delta = \arctan\left(\sin\alpha\tan\varepsilon\right),$

where $\varepsilon$ is the angle of the celestial equator to the ecliptic plane. Find an analogous relation $h = f(A)$ for the galactic equator in horizontal coordinates $(A,h)$ for an observer at latitude $\varphi = 49^\circ\ 34'$ at local sidereal time $\theta = 0^{\mathrm h}\ 51^{\mathrm m}$.
