... to Tokyo looks like it should mostly cross through Russia on a map of Europe. Instead, though, it flies almost over the north pole, taking the great circle route, saving hundreds of miles versus flying on a constant bearing. Curves of constant bearing (e.g., due southwest) are called loxodromes or r ...

MATH 131 Assignment 1
... Two points determine a unique straight line. Two straight lines determine a unique point. On a plane, two points determine a unique straight line. However, on a sphere, this is not always true. If the two points are situated at opposite ends of a sphere’s diameter, then they determine an infinity of ...

Cardinal direction
The four cardinal directions or cardinal points are the directions of north, east, south, and west, commonly denoted by their initials: N, E, S, W. East and west are at right angles to north and south, with east being in the clockwise direction of rotation from north and west being directly opposite east. Intermediate points between the four cardinal directions form the points of the compass. The intermediate (intercardinal, or ordinal) directions are northeast (NE), southeast (SE), southwest (SW), and northwest (NW). Further, the intermediate direction of every set of intercardinal and cardinal direction is called a secondary-intercardinal direction, the eight shortest points in the compass rose to the right, i.e. NNE, ENE, ESE, and so on.
