I used Desmos to calculate the position of stars

In this video I explain the idea of Declination and Right Ascension, as well as how to convert from altitude and azimuth into declination and right ascension. The entire problem and solution is visualised using the above desmos file, which shows the entire situation in 3 dimensions.
