Horizontal system of celestial coordinates

[suedenation]

given the latitude and longitude of a place, how can you use the horizontal system of celestial coordinates to find the location of the north celestial pole from an observer standing on that place?

For me, it's quite hard to imagine the Earth as a sphere, if 2-dimension, it's fine for me. How about you guys?

It's their latitude. For example, at the North Pole, latitude 90, the North celestial pole is 90 degrees from the horizon. From San Francisco, latitude 38 degrees, the north celestial pole is 38 degrees above the northern horizon. The south celestial pole is not visible from here, or anywhere north of the equator.
