Areas of all the degrees of latitude:
Examples: For 0° of latitude, the area in-between precisely latitude 0° North or South and precisely latitude 1° North or South. For 1° of latitude, the area in-between precisely latitude 1° North or South and precisely latitude 2° North or South.
NOTE: Areas of latitudes only for either the Northern or Southern Hemisphere, i.e. areas only for either latitude north or south, therefore for example, for the area of precisely latitude 41° North to precisely 42° N plus precisely 41° South to precisely 42° S, double the number.
